fix(watchdog): now the client could successfully send more msgs to watchdog instead of the only connection msg

- Add debug logging for watchdog operations
- Standardize message format for instance operations
- Improve TCP message handling with proper line termination
- Enhance error handling in watchdog operations
- Add proper cleanup of recvChan in sendMsg
- Update response handling in instance handlers
