Tool baru `deploy` menjalankan full pipeline:
1. Cek pending migrations → batalkan jika ada
2. Version bump package.json ke tag baru
3. Commit + push ke build/stg
4. Trigger publish.yml → polling hingga selesai
5. Trigger re-pull.yml → polling hingga selesai
6. Cek version di STG_URL vs local untuk konfirmasi
Env baru: STG_URL (staging app URL), VERSION_PATH (default /api/system/version)
