Scaffolder staleness check failed on Node 22

[github-actions]

The weekly scaffolder-staleness workflow failed on Node 22.

This means npm create @tournamental/app produces a project
that no longer builds or tests cleanly out of the box. A new
external contributor running the scaffolder right now would
see a broken project on first try, which is the #1 documented
developer-platform anti-pattern.

Run:
https://github.com/0800tim/tournamental/actions/runs/26033375360

Fix path:

1. Reproduce locally: node packages/create-tournamental-app/src/index.mjs --template plugin-scorer --name x --dir /tmp/x && cd /tmp/x && pnpm install && pnpm test
2. Bump template deps in packages/create-tournamental-app/templates/plugin-scorer/package.json.
3. Verify locally before pushing.
