chore: enhance pre-commit hooks with unsafe fixes and update line length

- Add --unsafe-fixes flag to ruff check for more aggressive auto-fixing
- Update isort line-length from 100 to 120 to match ruff configuration
- Keep Option A (industry standard): hooks auto-fix and fail commit
  so developer can review changes before re-committing

This ensures consistent formatting across the codebase while maintaining
visibility into what changes were made by the formatters.
