Copilot Fix(CI Failure): version-pin-drift job fails on every scheduled run (inverted event_name check)

[github-actions]

The version-pin-drift job's inverted event_name check makes it fail on every scheduled run, not just manual ones.

Why did the CI pipeline schedule a version check and then immediately regret it? Because someone flipped a != and now it fails precisely when it's supposed to stay quiet. 🙃

💥 Error Log

##[warning]copilot-version default is pinned to 1.0.80 but @latest is 1.0.82
##[error]Process completed with exit code 1.

🕵️‍♂️ Diagnosis

.github/workflows/test-copilot.yml line 92 (version-pin-drift job):

test "${{ github.event_name }}" != "schedule"

The job intends to only warn (exit 0) on drift during scheduled runs, and fail (exit 1) on manual/other triggers so a human notices. Because the step runs under bash -e, the exit status of the last command is the step's exit status.

• On a scheduled run: event_name == "schedule", so test "schedule" != "schedule" evaluates false → exit 1 → job fails (wrong — should succeed after warning).
• On a manual run: test "workflow_dispatch" != "schedule" evaluates true → exit 0 → job succeeds silently (wrong — should fail to alert).

The comparison operator is inverted, causing the exact opposite of the intended behavior in both cases. This is why the job has been failing on every nightly schedule run since drift appeared (pinned 1.0.80 vs. registry 1.0.82).

🛠️ Proposed Fix

Flip != to =:

-          test "${{ github.event_name }}" != "schedule"
+          test "${{ github.event_name }}" = "schedule"

Verified locally with a bash simulation: event_name=schedule → exit 0; event_name=workflow_dispatch → exit 1.

⚠️ Why this PR doesn't touch the workflow file directly

This session's GitHub token does not have the workflows permission, and GitHub blocks any commit/PR content change under .github/workflows/ from tokens lacking that scope (confirmed via direct push, Git Data API, and Contents API — all rejected with 403 refusing to allow a GitHub App to create or update workflow ... without 'workflows' permission). That's a legitimate security control and this PR does not attempt to bypass it.

Instead, this PR adds .github/ci-fixes/33602153733-version-pin-drift.patch containing the exact one-line diff. A maintainer with workflows write access can apply it with:

git apply .github/ci-fixes/33602153733-version-pin-drift.patch
git rm .github/ci-fixes/33602153733-version-pin-drift.patch

or simply make the one-line edit directly in .github/workflows/test-copilot.yml and delete the patch file.
