ci: treat all .github/workflows/** as code changes (#165)

Previously the path filter only included .github/workflows/ci.yml in the
"code" set. Editing any other workflow (auto-approve.yml, security.yml,
release.yml, etc.) caused the changes job to report "no code change",
which made unit-test / build / integration-test jobs skip.

This is a bug:
- Workflow changes can affect CI behavior, permissions, release process,
  auto-approve logic, etc.
- It caused PRs that touched auto-approve.yml (like the Scorecard parser
  fix) to have their required status checks skipped → merge blocked.

Fix: broaden the filter to .github/workflows/** (matching the pattern used
in other mature projects like patchloom).

Pure documentation changes (AGENTS.md, README, images/, etc.) are still
correctly skipped.
