* [pre-commit.ci] pre-commit autoupdate

updates:
- [github.com/astral-sh/ruff-pre-commit: v0.15.21 → v0.16.9](astral-sh/ruff-pre-commit@v0.15.21...v0.16.9)

* chore: pin ruff base rule selection

Ruff 0.16 expanded its default rule set, which surfaced ~50 new
violations. Pin the previous defaults explicitly so the version bump
does not change the lint policy, and revert the auto fixes made for
the newly enabled rules.
