- Header value truncation and count limits
- Automatic reconnect on socket disconnection
- Error reporting with throttling

Configuration directives:
- JsonSockLogEnabled: Enable/disable logging
- JsonSockLogSocket: Unix socket path
- JsonSockLogHeaders: List of headers to log
- JsonSockLogMaxHeaders: Maximum headers to log
- JsonSockLogMaxHeaderValueLen: Max header value length
- JsonSockLogReconnectInterval: Reconnect delay
- JsonSockLogErrorReportInterval: Error log throttle

Includes:
- Module source code (src/)
- Unit and integration tests (tests/, scripts/)
- Documentation (README.md, architecture.yml)
- Build configuration (CMakeLists.txt, Makefile)
- Packaging (deb/rpm)
