- Replace module-level env var globals with frozen Config dataclass
- Add pyproject.toml with project metadata, ruff, mypy, pytest config
- Expand unit tests from 11 to 30 (sanitize edge cases, SSH failure
modes, proxy forwarding, cleanup, auth loop edge cases)
- Fix all ruff and mypy findings
- Integration tests no longer need importlib.reload hack
- Dockerfile installs from pyproject.toml for consistency
