cleanup

Perform a complete code cleanup by following these steps:

Output Format: Use clear section headers, timestamps for each step, and progress indicators for long-running operations.

Tool Validation: First verify that required tools are installed (uv, ruff, mypy, pytest) and identify the project source layout (src/ or app/).

Checklist

• Ruff linting and formatting
• Mypy type checking
• Pytest suite
• Summary

1. Run ruff linting and formatting (parallel): Execute uv run ruff check src --fix and uv run ruff format src (or use app if that's the project structure) in parallel to automatically fix linting issues and format code. Re-run to verify all issues resolved.
2. Run mypy type checking: Execute uv run mypy src (or app) according to the project structure and fix any errors found. Re-run to verify fixes.
3. Run pytest via UV: Execute uv run pytest with appropriate timeout handling. If tests timeout, run them in logical sections (e.g., by directory or test file groups) to ensure all tests are executed and results are captured.

Error Handling: For each step, run the tool, fix issues found, then re-run to confirm the fix. If unable to fix after two attempts, report the specific error details and suggest manual fixes.

Update the checklist above as each step completes. Provide a final summary of all changes made.
