ci: disable recursive submodule checkout in PR workflows

CI/docs/codeql jobs failed before build/test because actions/checkout recursive submodule clone of vendor/zireael could not authenticate in Actions. These workflows do not require submodule materialization to run guardrails/build/tests/docs/codeql, so use non-recursive checkout.
