[q] feat(design-decision-gate): remove pull request review for design decision gate

[github-actions]

Removes the submit-pull-request-review safe-output and all PR review submissions (REQUEST_CHANGES / APPROVE) from the design-decision-gate workflow, as requested in #25830.

Changes

.github/workflows/design-decision-gate.md

• Removed submit-pull-request-review: max: 1 from safe-outputs frontmatter
• Removed REQUEST_CHANGES review call in Step 4a (no ADR found — block merge path)
• Removed APPROVE review call in Step 4b (ADR found and implementation matches path)
• Removed REQUEST_CHANGES review call in Step 4b (ADR found but divergences path)
• Updated trailing note from "marked as requesting changes" to reflect comment-only behaviour

Behaviour After Change

The gate now communicates exclusively via PR comments — no PR review state is set. This means:

• ADR requirements are surfaced via comments, not merge-blocking reviews
• Passing checks post an informational comment only
• The push-to-pull-request-branch and add-comment safe-outputs are unchanged

Validation

Compiled successfully: ✅ design-decision-gate

Warning

Protected Files — Push Permission Denied

This was originally intended as a pull request, but the patch modifies protected files. A human must create the pull request manually.

Protected files

• .github/workflows/design-decision-gate.lock.yml

• .github/workflows/design-decision-gate.md

The push was rejected because GitHub Actions does not have workflows permission to push these changes, and is never allowed to make such changes, or other authorization being used does not have this permission.
