Replace the nightly cron and its check-changes job with a debounce. Every push to main starts dev-image-debounce.yml, which waits out the 60-minute wait timer on the dev-image-debounce environment, then dispatches the Docker workflow only if main still points at its commit. A burst of merges now publishes one dev image, an hour after the last merge. The Docker workflow keeps only its tag and workflow_dispatch triggers, so its history holds real builds only. The debounce workflow deletes its own finished runs, so no-op runs don't pile up either. Requires the dev-image-debounce environment with a 60-minute wait timer (Settings → Environments).
