[QA-215] fix(ci): stop thank-you-note workflow failing on merged PRs

[nihal467]

Proposed Changes

Fixes the Thank You Note Generator workflow failing on every merged PR (e.g. run 29501202990 on #16569).

Symptom: The job fails at the Checkout PR branch step:

fatal: couldn't find remote ref refs/heads/QA-210-allow-qa-key-in-pr-title-jira-validation
failed to run git: exit status 128

Root cause: The workflow triggers on pull_request_target: closed. When a PR is merged, its head branch is typically deleted, so checkout_pr_branch.cjs cannot find the ref and hard-fails, aborting the job before the agent posts the thank-you note — defeating the workflow's entire purpose.

Fix: A single continue-on-error: true on the Checkout PR branch step. The checkout is not required for posting the note (the agent reads PR metadata via the API), and the downstream checkout_pr_success output already defaults to 'true', so the job proceeds and the note is posted.

       - name: Checkout PR branch
         id: checkout-pr
+        continue-on-error: true
         if: |
           github.event.pull_request

Scope: 3 lines added to the generated lock file; nothing else touched.

Greptile Summary

This PR fixes the Thank You Note Generator workflow aborting on every merged PR because the old checkout_pr_branch.cjs (gh-aw v0.42.14) called setFailed when it couldn't check out the already-deleted head branch, killing the job before the agent could post any note.

• Adds continue-on-error: true to the "Checkout PR branch" step so a failed git checkout (expected when the branch is deleted on merge) is treated as a non-fatal warning and the agent job continues normally.
• The existing checkout_pr_success output already defaults to 'true' via the || 'true' fallback when the step produces no output, so the downstream handle_agent_failure step in conclusion will not misinterpret this expected failure as a real error.

Confidence Score: 5/5

Safe to merge — a minimal, targeted change that lets the agent job continue past a git checkout failure that is expected on every merged PR.

The fix is a single continue-on-error: true directive on the one step known to abort when a merged PR's branch is deleted. The checkout_pr_success output already has a || 'true' fallback that correctly represents 'checkout skipped, proceed anyway' to downstream jobs. No logic changes, no new secrets, no permission changes.

No files require special attention.

blanket-suppress failures via continue-on-error. Update the checkout and
checkout_pr_success handling so only an expected deleted head branch is treated
as successful, while authentication, API, network, and other checkout failures
propagate or stop downstream execution; do not allow missing step output to

[nihal467]

Filed upstream tracking issue: github/gh-aw#46768.

Summary of why this PR keeps the continue-on-error: true workaround instead of a "cleaner" fix:

• checkout: false in frontmatter doesn't help. It only disables the default actions/checkout at job start, not the PR-specific Checkout PR branch step (which uses actions/github-script + checkout_pr_branch.cjs). gh-aw currently has no flag to skip that step.
• Regenerating with gh aw compile isn't viable in-scope. The locally-installed gh-aw is v0.77.5 vs the v0.42.14 that produced the current lock file, so recompilation adds ~500 lines of unrelated framework churn and still emits the same failing step.
• Manually deleting the step from the lock file is fragile — the next gh aw compile silently reintroduces it.

The one-line continue-on-error: true patch is the lowest-friction fix that survives future regenerations (any upgrade would have to actively remove the attribute). Once the upstream issue is addressed, this workaround can be dropped in a follow-up.
