Pull request overview

This PR introduces a Python “table” formatter for aligning repeated tuple/call rows (e.g., config tables), integrates it into pre-commit + CI, and updates various template/example configs to use the aligned layout with # fmt: off/on guards so Ruff formatting won’t undo the alignment.

Changes:

• Add scripts/format_python_tables.py plus CI regression tests to keep formatting stable.
• Wire the formatter into .pre-commit-config.yaml and run its tests in GitHub Actions CI.
• Reformat multiple template/example config tables and adjust VS Code template formatting settings.
