Test: Validate CI workflow changes from PR #163

[brycelelbach]

Summary

Temporary PR to validate the CI workflow changes landed in PR #163. This branch intentionally triggers all 5 CI checks to verify:

1. YAML check -- bad.yaml with indentation errors and duplicate keys
2. Link check -- bad-link.md with a broken GitHub URL
3. Notebook format check -- bad-notebook.ipynb with non-canonical format, outputs, and execution counts
4. Git LFS check -- not-lfs-tracked.png added without LFS tracking
5. Git signature check -- One commit is deliberately unsigned

What to verify

• All 5 test workflows trigger on the push event (not pull_request)
• All 5 test workflows fail as expected
• All 5 PR comment workflows fire and post comments with correct formatting
• PR comments include collapsible <details> blocks with error output
• Concurrency groups work (push again to verify superseded runs are cancelled)

Cleanup

Delete this PR and branch once validation is complete.

Unsigned commits

• 4ae7bff: Test: Add unsigned commit to trigger signature check. (unsigned)

How to fix:

1. Configure commit signing (if not already done):

   # For GPG signing
   git config --global commit.gpgsign true
   
   # Or for SSH signing (Git 2.34+)
   git config --global gpg.format ssh
   git config --global user.signingkey ~/.ssh/id_ed25519.pub

2. Re-sign your commits:

   git rebase -i origin/main --exec "git commit --amend --no-edit -S"
   git push --force-with-lease
