chore(pre-commit): bump ruff pin v0.15.9 → v0.15.14

Lock-step with pyproject.toml `[project.optional-dependencies].dev`
(ruff bumped from 0.15.9 → 0.15.14 via PR #1583). The
`.pre-commit-config.yaml` header explicitly requires this rev to
match the pyproject pin — without this bump, contributors who run
`pre-commit install` will hit the same version-mismatch debacle this
PR was opened to prevent.
