Add a uv lock --check guard in two places so a stale uv.lock cannot be
committed unnoticed (as happened with the groundroute extra):
- pre-commit: a local uv-lock-check hook, scoped to the backend
pyproject.toml files and uv.lock.
- CI: a "Check uv.lock is in sync" step in the lint-backend job, run
before uv sync so the install step cannot mask a stale lock by
regenerating it.
* feat(dev): add pre-commit hooks for ruff, eslint, and prettier
* fix: use local uv-based ruff hooks and uv run for pre-commit install
