DokPloy rm-rf's the host code dir on every redeploy, orphaning the
long-running cron container's ./content and ./.git bind mounts (pinned to
the now-deleted inode). The wiki export then spins forever in fs.mkdir
against the dead directory and never commits.
mount-guard.sh detects a stale mount (directory hard-link count < 2 = a
deleted inode) and re-binds it via docker restart, run every 15 min from
cron and once at the top of export-content-cron.sh as a fast-fail.
Alpine crond doesn't inherit the container environment, so
OUTLINE_API_TOKEN and other vars were missing. Dump env at
startup and source it in each cron entry.
- Add cron service to docker-compose with backup (3 AM) and export (4 AM) schedules
- Remove redundant content/articles/ and content/curriculum/ (now in Outline, exported to content/wiki/)
- Fix env var mismatch: support both OUTLINE_API_KEY and OUTLINE_API_TOKEN
- Drop updatedAt from export frontmatter to reduce noisy commits
- Add backups/ to gitignore
