Motivation

• Enable the RUF100 lint rule and remove locally-suppressed # noqa annotations to bring code into alignment with stricter linting.
• Clean up small formatting inconsistencies to improve readability without changing runtime behavior.

Description

• Add "RUF100" to the select list in pyproject.toml to enable the new ruff rule.
• Remove several redundant # noqa comments across files including src/trimmy/__main__.py, src/trimmy/apps/desktop/control_server.py, src/trimmy/apps/desktop/main_window.py, src/trimmy/rendering/application/render_segments_use_case.py, and src/trimmy/rendering/infrastructure/ffmpeg.py.
• Apply minor formatting and whitespace adjustments (reflowed Annotated parameters and small function/exception handling formatting) with no changes to logic or public APIs.

Testing

• Ran the linter with the updated configuration via ruff and the codebase passed with the new RUF100 selection.
• Ran the test suite with pytest and all tests completed successfully.
