docs: update README, CONFIG, EXTEND for config/dialer refactoring

Replace the five-goroutine session model (RunDialer, RunKeepalive,
RunReader, RunHeartbeatForwarder, RunStopMonitor, Session) with a single
DefaultWorker.runSession method containing two select loops: one
pre-connection and one connected. Ephemeral dial goroutines replace
RunDialer; the keepalive timer and heartbeat reset are inlined. No
exported building-block symbols remain.

Consolidate worker_dialer_test.go, worker_session_test.go, and
worker_start_test.go into worker_test.go. Add seven new behavioral
tests covering dial failure, keepalive-driven dial replacement,
pre-connection stop, message delivery with timestamp, sustained
activity and pong resetting the keepalive timer, keepalive-triggered
reconnect, and nil connection pointer after disconnect.
Update EXTEND.md and README.md to remove references to the deleted

building blocks and document the single worker replacement pattern

 All configuration is done through option functions applied at construction time. Invalid values return errors at application time; configs produced through `NewXConfig` constructors are validated at construction and cannot be saved in an invalid state.
 
-There are three config scopes. `ConnectionConfig` governs a single WebSocket connection: its write behavior, ping interval, buffers, and retry policy. `WorkerConfig` governs a single worker's behavior, with separate types for inbound and outbound. `PoolConfig` bundles a connection config, a worker config, and an optional worker factory — it is a thin container.

 Logging can be controlled independently at the pool, worker, and connection levels. Each scope has a `LoggingEnabled` flag and a `LogLevel` override. When `LoggingEnabled` is false, no logger is constructed for that scope regardless of what handler is passed to the pool. When `LogLevel` is set, it overrides the handler's own level filter for that scope only, using a wrapping handler that enforces the minimum level before delegating. When `LogLevel` is nil, the handler's own level filtering applies unchanged.

 **`Inbox`** The shared channel that delivers received messages to the pool's consumer. All peers in the pool deliver to the same inbox channel. Workers must include their peer ID in each `InboxMessage`.
 
-**`Events`** The shared channel for lifecycle events. Outbound workers emit `outbound.EventConnected` and `outbound.EventDisconnected` directly. Inbound workers do not touch this channel directly; instead they call `OnExit`, and the pool translates the exit kind into the appropriate event. All events include a timestamp in the `At` field.
+**`Events`** The shared channel for lifecycle events. Workers emit `honeybee.EventConnected` and `honeybee.EventDisconnected` directly. All events include a timestamp in the `At` field.
 
 **`InboxCounter`** An atomic counter owned by the pool. Workers must increment this once for each message forwarded to `Inbox`. The pool reads it in `Stats()`.
 
-**`OnExit` (inbound only)** Must be called exactly once when an inbound worker exits on its own initiative — that is, when the peer closed the connection or the watchdog fired, not when `Stop` was called. The pool wraps the underlying function in a `sync.Once` as a safety net, but a well-behaved worker calls it once. Calling `OnExit` removes the peer from the pool's registry and emits the appropriate event.
-
 **`Handler`** The `slog.Handler` passed to the pool constructor. The pool constructs and injects scoped loggers before calling the factory, so most workers will use the logger they receive from the factory rather than constructing one from `Handler` directly. `Handler` is available for workers that manage sub-components that need their own loggers.

-
-The pool calls the factory under its write lock when `Add` or `Replace` is called. The factory must return without blocking. The pool constructs `logger` from the worker logging config before calling the factory; pass it to your worker or ignore it.
-
-The factory is set via `inbound.WithWorkerFactory` on the pool config.
-
-### Building Blocks
-
-The default inbound worker is assembled from these exported functions. Each can be reused, replaced, or wrapped independently.
-
-**`RunReader(ctx, onExit, conn, messages, heartbeat, logger)`** Reads from `conn.Incoming()` until the channel closes or `ctx` is cancelled. Forwards each message to `messages` and sends a signal on `heartbeat` for each message received. When the channel closes, classifies the exit — clean disconnect, unexpected close, or read error — and calls `onExit` with the appropriate `WorkerExitKind`. Does not call `onExit` on context cancellation.
-
-**`RunHeartbeatForwarder(ctx, conn, heartbeat, logger)`** Reads from `conn.Heartbeat()` and forwards each signal to `heartbeat`. This propagates pong replies from the connection layer into the worker's heartbeat channel, so pongs reset the inactivity watchdog alongside data messages.
-
-**`RunQueue(id, ctx, in, out, maxQueueSize, droppedCount, bufferDepth)`** Buffers messages between the reader and the forwarder. When `maxQueueSize` is positive and the queue is full, the oldest message is dropped and `droppedCount` is incremented. When `maxQueueSize` is zero, the queue grows without bound. `bufferDepth` is an `*atomic.Int64` maintained as the current number of items in the queue.
-
-**`RunForwarder(id, ctx, messages, inbox, workerProcessedCount, poolInboxCount)`** Reads from `messages` and writes to `inbox`. Increments both counters on each successful delivery.
-
-**`RunWatchdog(ctx, onInactive, heartbeat, timeout, logger)`** Monitors `heartbeat`. Resets a timer on each signal. When the timer fires, calls `onInactive(ExitPolicy)`. When `timeout` is zero, the watchdog is disabled: it drains `heartbeat` without acting and exits when `ctx` is cancelled.
-
-### Replacement Patterns
-
-**Swap one block.** Embed `*inbound.DefaultWorker`, override `Start`, reuse the goroutines you want unchanged, and substitute your own implementation for the one you are replacing. For example, to tag every forwarded message with a sequence number, reuse `RunReader`, `RunQueue`, and `RunWatchdog` verbatim, and write a custom forwarder.
-
-**Wrap the plugin.** Intercept `Inbox` by substituting a channel you own, process messages, then forward to the original. The worker signature is unchanged; you compose behavior by controlling what the building blocks see.
-
-**Implement from scratch.** Satisfy the `Worker` interface directly. The only obligations are the behavioral contracts on `Start`, `Stop`, `Send`, `Stats`, and `OnExit` described above.

-### Building Blocks
+### Replacing the Worker
 
-**`RunDialer(id, ctx, pool, dial, newConn, logger)`** Listens on `dial` for connection requests. On each signal, calls `connect` to dial a new `*transport.Connection`. While a dial is in progress, drains additional `dial` signals so that at most one dial runs at a time. On failure, logs the error and waits for the next `dial` signal. On success, sends the connection on `newConn`. Exits when `ctx` is cancelled.
+Satisfy the `Worker` interface and register your implementation via `honeybee.WithWorkerFactory`. Your worker is responsible for the full connection lifecycle: dialing and redialing, managing connection state, forwarding received messages to `pool.Inbox`, emitting `EventConnected` and `EventDisconnected` to `pool.Events`, and incrementing `pool.InboxCounter` for each message forwarded.
 
-**`RunKeepalive(ctx, heartbeat, keepalive, timeout, logger)`** Monitors `heartbeat`. Resets a timer on each signal. When the timer fires, sends a signal on `keepalive` to notify the session that the connection should be replaced. When `timeout` is zero, keepalive is disabled: it drains `heartbeat` without acting and exits when `ctx` is cancelled.
+`DefaultWorker`'s source is the authoritative reference for how those responsibilities are met.
-
-**`RunReader(ctx, onStop, conn, messages, heartbeat, logger)`** Reads from `conn.Incoming()` until the channel closes or `ctx` is cancelled. Forwards each message to `messages` and sends a signal on `heartbeat`. On exit, calls `conn.Close()` and then `onStop`.
-
-**`RunHeartbeatForwarder(ctx, conn, heartbeat, logger)`** Reads from `conn.Heartbeat()` and forwards each signal to `heartbeat`. Propagates pong replies into the worker's heartbeat channel so pongs reset the keepalive timer alongside data messages and sends.
-
-**`RunStopMonitor(ctx, onStop, conn, keepalive, logger)`** Waits for either `ctx.Done` or a signal on `keepalive`. On either, calls `conn.Close()` and then `onStop`. This is how a keepalive expiry propagates into a session tear-down.
-
-**`RunForwarder(id, ctx, messages, inbox, workerProcessedCount, poolInboxCount)`** Reads from `messages` and writes to `inbox`. Increments both counters on each successful delivery. Identical in behavior to the inbound variant.
-
-**`Session`** The coordination struct that ties the above blocks together for one connection lifecycle. `Session.Start` runs a loop: request a dial, wait for a connection, run `RunReader`, `RunHeartbeatForwarder`, and `RunStopMonitor` concurrently, wait for them to finish, emit `EventDisconnected`, sleep for `ReconnectDelay`, then repeat. `Session` is exported so it can be embedded or used directly in a custom worker.
-
-### Replacement Patterns
-
-**Swap one block.** The most common case is replacing `RunReader` to intercept or annotate inbound messages, or replacing `RunKeepalive` with a different activity metric. Reuse `Session` for the connection lifecycle and substitute the one goroutine you need to change.
-
-**Replace the session loop.** Construct your own loop using `RunDialer`, `RunKeepalive`, and the session-level blocks. This gives you control over reconnection logic, back-off behavior, or multi-connection strategies while keeping the lower-level I/O blocks intact.
-
-**Implement from scratch.** Satisfy the `Worker` interface directly. You are responsible for dialing, managing connection state, forwarding messages to `pool.Inbox`, emitting `EventConnected` and `EventDisconnected` to `pool.Events`, and incrementing `pool.InboxCounter`.
 
 ## Factory Constraints
 
-Factories for both pool types are called while the pool holds its write lock. Two constraints follow from this directly.
+The factory is called while the pool holds its write lock. Two constraints follow from this directly.
 
 **Factories must not block.** Any operation that could wait — dialing a connection, acquiring another lock, reading from a channel — will deadlock or stall the pool. All blocking work belongs inside `Start`, not inside the factory.
 
-**Factories must not call pool methods.** `pool.Add`, `pool.Send`, `pool.Remove`, and similar methods all acquire the same lock the factory is called under. Calling them from the factory will deadlock.

 ## What This Library Does
 
-Honeybee is a reliable and simple library for managing websocket connections and pools.
+Honeybee is a minimal, general-purpose WebSocket transport library.
 
-- Handles websocket connections and pools cleanly and safely.

-## Usage
+## Outbound Pool
 
-### Bare Connection
+The pool connects to peers by their URLs and keeps them connected. It reconnects automatically when a connection drops and proactively refreshes inactive connections.
 
-Use `transport` directly when you need one socket and do not want pool semantics.
+```go
+import "git.wisehodl.dev/jay/go-honeybee"
+
+pool, err := honeybee.NewPool(ctx, nil, handler)
+if err != nil { /* handle error or panic */ }
+defer pool.Close()
+
+if err := pool.Connect("wss://peer.example.com"); err != nil { /* handle error */ }
+
+go func() {
+    for msg := range pool.Inbox() {
+        // msg.ID            is the normalized URL
+        // msg.Data          is the payload
+        // msg.ReceivedAt    is the timestamp
+    }
+}()
+
+go func() {
+    for ev := range pool.Events() {
+        // ev.At             is the event timestamp
+        switch ev.Kind {
+        case honeybee.EventConnected:
+        case honeybee.EventDisconnected:
+        }
+    }
+}()
+
+pool.Send("wss://peer.example.com", []byte("hello"))
+```
+
+**Usage Notes:**
+
+ URLs are normalized by the pool. `wss://peer.example.com`, `wss://peer.example.com/`, and `WSS://Peer.Example.Com:443` all identify the same peer. `honeybee.NormalizeURL` is also available directly if you need to use the same URLs as keys elsewhere.
+
+Every time a connection is established, `honeybee.EventConnected` is emitted. Every time a connection drops for any reason, `honeybee.EventDisconnected` is emitted. A peer that reconnects three times produces three Connected/Disconnected pairs.
+
+Keepalive is configured via `honeybee.WithKeepaliveTimeout`. The worker records a heartbeat on every inbound message, every successful send, and every received pong. If no heartbeats arrive before the keepalive timer fires, the connection is proactively disconnected and reconnected. When set to zero, keepalive is disabled.
+
+After a disconnect, the worker waits for `ReconnectDelay` before attempting the next connection. The default is 2 seconds. Set to zero in tests or when you need immediate reconnection.
+
+`Send` returns `ErrConnectionUnavailable` during the gap between a disconnect and the next successful reconnect. Callers should wait for `EventConnected` before retrying and maintain their own write buffers if needed.
+
+Dial failures are handled internally by the worker's retry logic and documented in structured logs. These do not stop the pool; it continues retrying according to the connection's retry config.
+
+## Server-Side Usage
+
+### Connection
+
+Use `transport.NewConnectionFromSocket` when your HTTP upgrade handler gives you an open socket. The connection starts in `StateConnected`; do not call `Connect`.
+
+```go
+import "git.wisehodl.dev/jay/go-honeybee/transport"
+
+// wsConn is a *websocket.Conn from your upgrade handler
+conn, err := transport.NewConnectionFromSocket(wsConn, nil, logger)
+if err != nil { /* handle error */ }
+defer conn.Close()
+
+go func() {
+    for data := range conn.Incoming() { // data: []byte
+        // process incoming messages
+    }
+}()
+
+go func() {
+    for err := range conn.Errors() {
+        // log or handle disconnects / read errors
+    }
+}()
+
+// Send can be called concurrently
+conn.Send([]byte("hello"))
+```
+
+`Send` is safe for concurrent callers. `Close` is idempotent and safe to call from any goroutine.
+
+When the reader exits, exactly one classified error reaches `Errors()` before the channel closes.
+
+- `ErrPeerClosedClean` for normal closure
+- `ErrPeerClosedUnexpected` for abnormal close codes
+- `ErrReadError` for anything else
+
+Pass an `*slog.Logger` as the third argument to get structured logs. Pass nil to disable logging entirely.
+
+### IdleWatchdog
+
+The watchdog helper detects clients that have gone silent. Wire activity signals from your `Incoming()` consumer, on each Send() call, and from the connection's `Heartbeat()` channel into it, and provide a callback to invoke when the timeout fires. Feeding all three sources means a client that neither sends or receives data but still responds to pings will not be considered idle. Since there is no reconnect loop on the server side, the typical callback is `conn.Close()`.
+
+```go
+import "time"
+
+activity := make(chan struct{}, 1)
+
+signal := func() {
+    select {
+    case activity <- struct{}{}:
+    default:
+    }
+}
+
+// Feed data messages:
+go func() {
+    for data := range conn.Incoming() {
+        signal()
+        // process data
+    }
+}()
+
+// Feed sends:
+func SendWithHeartbeat(conn *Connection, data []byte) error {
+    err := conn.Send(data)
+    if err != nil {
+	    return err
+    }
+    signal()
+    return nil
+}
+
+// Feed pong heartbeats:
+go func() {
+    for range conn.Heartbeat() {
+        signal()
+    }
+}()
+
+// Start the watchdog:
+go transport.IdleWatchdog(ctx, activity, 30*time.Second, func() {
+    conn.Close()
+})
+```
+
+When no activity signal arrives within the timeout, `onTimeout` is called once and the watchdog exits. When `ctx` is cancelled, the watchdog exits without calling `onTimeout`. When the timeout is zero or negative, the watchdog drains activity signals and waits for `ctx` to be cancelled without ever firing.
+
+## Bare Connection
+
+Use `transport.NewConnection` when you need a single outbound connection without pool semantics — for example, a one-shot query or a custom use-case. It adds several conveniences over a raw socket: a retry loop with exponential backoff, concurrent-safe writes, automatic write deadline enforcement, classified disconnect errors, and observable connection state.

-
-`Add`, `Replace`, and `Remove` do not emit events. Events are emitted only when a worker exits on its own, either when the peer closed the socket or it was determined to be inactive.
-
-Use `Replace` if you need to swap the socket for a peer while keeping its ID. No events are emitted during this process.
-
-The watchdog is configured via `inbound.WithInactivityTimeout`. When set to zero, it is disabled. When set, the watchdog observes message traffic and disconnects the peer if no messages arrive within the configured duration. The watchdog is disabled by default, meaning connections persist until manually removed or remotely terminated.

 ## Ping-Pong Heartbeats
 
 Connections send periodic WebSocket ping frames and listen for the corresponding pong replies. A received pong registers as a heartbeat signal within the worker.
 
-For inbound workers, pong-derived heartbeats reset the inactivity watchdog timer alongside data messages. A peer that sends no data but responds to pings will not be evicted.
+Pong-derived heartbeats reset the keepalive timer alongside data messages and sends. A peer that sends no data but responds to pings will not be disconnected and reconnected by the keepalive mechanism.
 
-For outbound workers, pong-derived heartbeats reset the keepalive timer. A peer that sends no data but responds to pings will not be disconnected and reconnected by the keepalive mechanism.
+The ping interval is configured via `transport.WithPingInterval` on the `transport.ConnectionConfig`. Import `git.wisehodl.dev/jay/go-honeybee/transport` to construct a `ConnectionConfig`, then pass it to the pool by value via `honeybee.WithConnectionConfig`, or supply it directly to `NewConnection` and `NewConnectionFromSocket`. The default is 20 seconds. Set to zero to disable pings entirely, in which case only data messages and outbound sends generate heartbeats.
