Improve error handling and logging in Techhider and TinyProtocol

Refined logging messages for clarity by replacing "Techhider" with "PacketInterceptor" where appropriate. Adjusted error handling in `TechhiderbugCommand` by removing redundant `flush` calls and properly logging exceptions during bug report generation. These changes aim to enhance maintainability and debugging.
