Fix linter issues and update integration test

- Remove unused imports (signal, yaml, os, socket, ConfigLoader)
- Remove unused variable assignments in argument parsers
- Update integration test to send initialize request first
- Fix test to match new server mode behavior

All unit tests pass, integration test needs initialize handshake.
