[CI/CD] Sync develop-auto CI workflows to develop to restore CI parity

[chronoai-shining]

Background

The /sa-implement daemon preflight aborts with code 64 (CI parity) because two workflow files differ between develop and develop-auto:

• .github/workflows/ci.yml — codecov/codecov-action@v4 → v7 (×4)
• .github/workflows/changeset-release.yml — actions/create-github-app-token@v2 → v3 (×1)

The divergence is entirely the Dependabot GitHub-Actions bump from #620, which merged to develop but never reached develop-auto. There are no logic/gate changes — only action version bumps.

Purpose

Restore CI parity so PRs into develop-auto are gated by the same checks as develop, unblocking the autonomous implementation loop. Minimal, surgical fix: copy only the two diverged workflow files from develop into develop-auto (no full branch recreate).

Affected Files

• .github/workflows/ci.yml
• .github/workflows/changeset-release.yml
• .changeset/*.md (empty changeset — CI-only, no version bump)

Implementation Specification

1. Branch off origin/develop-auto (base must stay develop-auto; its unpromoted history is preserved).
2. git checkout origin/develop -- .github/workflows/ci.yml .github/workflows/changeset-release.yml.
3. Add an empty changeset (bun changeset --empty equivalent).
4. Open PR targeting develop-auto; merge when green.

Verification Checklist

• git diff origin/develop...HEAD -- .github/workflows/ci.yml .github/workflows/changeset-release.yml is empty after the sync.
• PR CI green on develop-auto.
• auto-preflight.sh ci-parity check passes (no WORKFLOW_FILE_DIVERGENCE).

Definition of Done

• develop-auto's ci.yml and changeset-release.yml byte-match develop's.
• /sa-implement daemon preflight passes (no code 64).

Resolved by #1111 (squash-merged into develop-auto). develop-auto's ci.yml + changeset-release.yml now byte-match develop; CI parity restored. Closing manually since the PR merged to develop-auto rather than the default branch (no auto-close keyword fires there).
