fix(ci): flip all-required continue-on-error to false — unblocks all open PRs

Phase 4 (RFC #219 §1): all-required sentinel now always reports result to
the Gitea Actions API. Phase 3 safety preserved via platform-build's own
continue-on-error: true (mc#664 interim mask; re-flip blocked on PR #669
fix-forward landing). Cancelled results from CoE-masked platform-build
failures are intentionally excluded from the sentinel bad-list so PRs
remain unblocked while the interim mask is active.

- all-required: continue-on-error: true → false
- platform-build comment updated to reference PR #669 fix-forward cascade
- Inline script comments updated to remove Phase 3 terminology

Closes: #714
