## Summary
- Removes the last in-process \`setInterval\` (\`server/snapshots.ts\` 24h loop) and replaces it with an external HTTP cron job via Forgejo Actions
- Adds automated standings sync + conditional simulation: syncs every 2h, only simulates when standings actually changed (detected by comparing \`gamesPlayed\`/\`leagueRank\` before upsert)
- Adds \`GET /healthz\` for Docker healthcheck (Phase B prerequisite)
## What's new
| Endpoint | Triggered by | What it does |
|---|---|---|
| \`POST /admin/jobs/run-daily-snapshots\` | Forgejo schedule \`5 0 * * *\` | Creates daily fantasy standings snapshots for all active/draft seasons |
| \`POST /admin/jobs/sync-and-simulate\` | Forgejo schedule \`0 */2 * * *\` | Syncs standings from external APIs; runs simulation only if standings changed |
| \`GET /healthz\` | Docker / Traefik | Returns 200 \`{ok:true}\` when DB reachable, 503 otherwise |
Both cron endpoints are protected by \`X-Cron-Secret\` header (set \`CRON_SECRET\` in Forgejo repo secrets + production env).
## Schema changes (migration 0118)
Two new nullable columns on \`sports_seasons\`:
- \`standings_last_changed_at\` — written by \`syncStandings()\` when data actually changes
- \`last_simulated_at\` — written by the cron job after a successful simulation run
## Deployment notes
1. Add \`CRON_SECRET\` to Forgejo repo secrets (generate with \`openssl rand -hex 32\`)
2. Add same value to production environment
3. Migration runs automatically via the \`migrate\` container on deploy
## Test plan
- [ ] \`curl -X POST https://brackt.com/admin/jobs/run-daily-snapshots -H "X-Cron-Secret: ..."\` → 200 \`{total, succeeded, errors}\`
- [ ] \`curl -X POST https://brackt.com/admin/jobs/sync-and-simulate -H "X-Cron-Secret: ..."\` → 200 with \`synced\`/\`unchanged\`/\`simulated\` breakdown
- [ ] \`curl https://brackt.com/healthz\` → 200 \`{ok:true}\`
- [ ] Verify Forgejo workflow runs appear in Actions tab after merge
- [ ] Kill web process mid-day; confirm external cron still fires (no in-process dependency)
