build(env): pin Python version to 3.12 and update CI workflow

- Pin requires-python to "==3.12.*" in pyproject.toml
- Update .github/workflows/ci.yml to pin Python to 3.12 and cache on uv.lock
- Replace manual uv pip installs with 'uv sync --extra dev' in CI environment
- Enable pytest execution step in CI since test suite is now present
- Regenerate uv.lock with pinned Python version
