v0.1.5 - Reconnect in retries

Release v0.1.5

- Add device identifiers to all log messages for multi-device support
- Add automatic reconnection in retry logic for self-healing operations
- Add request serialization to prevent concurrent operations
- Fix connection handling with proper disconnect on errors
- Fix protocol padding handling for type 0x00 messages

Network efficiency: Auto-reconnect uses 29% less traffic than keepalive
pings for typical Home Assistant polling intervals (30s).

Log format now includes device identifier: [10.20.20.12] or [device_id]
