Merge branch 'dev' into pr-container-images

- cleanup: pull_request -> pull_request_target so fork PRs trigger cleanup
- cleanup: add workflow_dispatch for manual stale image deletion
- publish: skip fork PRs (no packages:write) and draft PRs
- publish: add ready_for_review trigger
- publish: add workflow_dispatch for manual fork PR builds
- publish: unified tag derivation step
