test: validate all metadata.yaml files against schema in pytest

- pyproject.toml with pytest>=8 in [dependency-groups.dev] so
  uv run --group dev pytest resolves without a global install
- tests/__init__.py and tests/conftest.py skeleton referencing issue #162
- pre-commit local hook runs pytest tests/ on Python file changes;
  exit code 5 (no tests collected) is treated as success so commits
  are not blocked while the test suite is being built out
