Subject: [PATCH] feat(cinny-deploy): fail and alert when a deployed page
 references missing files

After copying, check every script/stylesheet the app and call pages
reference (src/href in both index.html files) exists in the webroot. If
any is missing, log it, post an alert with the upstream checker's Matrix
credentials (/etc/cinny-monitor.env, best effort) and exit 1. This would
have caught the 2026-10-20 call-page outage at deploy time.
