v0.4.1 — Structured Logging

New Features

• Verbose logging: Server now supports structured logging via Go stdlib log/slog. Two new flags control output:

  • -log-level — debug | info | warn | error (default info)
  • -log-format — text | json (default text)

• MCP tool call tracing: Every tool call is logged with entry/exit timestamps, duration, session/reader IDs, and error flags. Go-level errors are logged at Error level; IsError results stay at Debug.

• Session lifecycle logs: Session start, exit, and termination events emit Debug-level records with session ID and exit code.
