Footer becomes a changelog chip and shows an 'Update available' badge when a newer APP_VERSION exists upstream. Detection reads src/lib/version.ts from the Gitea default branch (dms model) and compares — self-contained, no OTM control plane. Adds src/lib/update-check.ts and GET /api/version (also a running-version probe for the upcoming one-click rebuild). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
