-1. **Fix linting issues**: Run `uv run ruff check --fix` to address 20 unused import and variable warnings
-2. **Validate fixes**: Ensure all tests still pass (149 tests) after cleanup
-3. **Confirm application functionality**: Test that `uv run hosts` still works perfectly
-4. **Commit clean state**: Create commit with "Fix linting issues" once cleanup is complete
