Reconnecting

data class Reconnecting(val attempt: Int, val lastError: MqttException? = null) : ConnectionState

Attempting to re-establish a lost connection.

Entered automatically when the connection drops unexpectedly and MqttConfig.autoReconnect is true. Uses exponential backoff between attempts (configurable via MqttConfig.reconnectBaseDelayMs and MqttConfig.reconnectMaxDelayMs). Subscriptions are automatically re-established on successful reconnection.
