 ### Retry
 
 The retry policy governs the `Connect()` call only. It does not affect worker reconnection, which is controlled by `ReconnectDelay` on the worker config.

+Overrides the dialer for a single `Connect` call. Passed as a variadic option: `pool.Connect(id, honeybee.WithDialer(d))`. When provided, it takes precedence over the dialer resolved from `ConnectionConfig`. Existing callers that pass no options are unaffected.
