Patrick SelamyandClaude Opus 4.5 1f4f1fa557 fix: resolve linting and formatting issues for CI
- Use contextlib.suppress instead of try/except/pass (SIM105)
- Prefix unused fixture arguments with underscore (ARG002)
- Replace asyncio.TimeoutError with TimeoutError (UP041)
- Apply ruff formatting to all files
