Infiland 057f2bb8b3 fix: add reconnection policy to Redis subscriber to prevent ghost state (#708)
* fix: add reconnection policy to Redis subscriber to prevent ghost state

- Add ReconnectPolicy::new_exponential(0, 100, 30_000, 2) to the subscriber builder, unlimited retries with exponential backoff (100ms min, 30s max)
- Add on_reconnect handler that signals the listener loop to force a subscription reset, re-subscribing to all topics on the new connection
- Add warn-level logging to on_error for all Redis subscriber errors (previously only Canceled was handled, others were silently ignored)

* Auto-manage subscriptions on reconnect

Call subscriber.manage_subscriptions() so the subscriber will automatically re-subscribe tracked channels after a Redis reconnect. Remove the manual reconnect channel and on_reconnect handler along with the select branch that forced SubscriptionStateChange::Reset.
