Devlog-Endpoint: Bot postet Devlogs selbst — gebrandet, mit Bilder-Grid

- POST /webhooks/devlog/<secret> — Discord-Webhook-kompatibel (JSON + Multipart),
  devlog.py braucht nur die neue URL in tools/.devlog_webhook
- Bot postet Embed in Brand-Gelb mit 'D4RKST3R // DEVLOG'-Footer, bis zu 4 Bilder
  als Grid (Embed-Gruppierung über gemeinsame URL)
- Direkt-Archivierung inkl. Bilder (kein Umweg über den Live-Listener)
- Neue Env-Var DEVLOG_POST_SECRET, README-Abschnitt neu geschrieben
