Module protocol 

Hook protocol abstraction for multi-agent support.

Each coding agent sends/receives hook JSON in a different format. The HookProtocol trait encapsulates these differences so the core permission logic works identically regardless of which agent is calling.

Most methods have default implementations that handle the common case. Adding a new agent typically requires overriding only HookProtocol::agent and HookProtocol::parse_tool_use. Override format methods only if the agent uses a non-standard output format.
