chore(ci): noop workflow to clear stale red badge

After PR #5 moved all 5 upptime workflows out of .github/workflows/,
no CI fires on push to main. The dashboard's CI status badge is
sticky on the LAST CI run, which was the broken upptime cron from
before the disable — so the repo displays a permanent red X.

Add a tiny noop workflow that prints why the repo is idle and
exits 0. Fires on push + daily cron so the badge stays accurate.

Replacement tracked in internal#97 (external uptime monitor RFC).
