Order config validators before ruff in pre-commit

Ruff loads its config from pyproject.toml, so a malformed pyproject.toml
makes ruff abort with a parser error instead of the clean check-toml
message. Running check-toml/check-yaml first (with fail_fast) ensures
syntax errors are reported by the dedicated validator, consistently
between local commits and CI's --all-files run.
