Community-Paket: Playtester-Programm, Starboard, Screenshot-Galerie

- Playtester: /playtester-setup postet Bewerbungs-Embed mit 🧪-Button;
  Toggle vergibt Rolle + DB-Eintrag; Liste + Rollen-Auswahl auf der Setup-Seite
- Starboard: ab konfigurierbarem ⭐-Schwellwert Repost als Embed in den
  Best-of-Kanal (Dedupe, kein Selbst-Boarding); neue Intents/Partials für Reaktionen
- Galerie: Bilder aus dem Screenshot-Kanal lokal archiviert (live + /galerie-backfill,
  Delete-Sync, Bot reagiert mit ⭐) → öffentliche /galerie-Seite mit Hover-Grid
- Setup-Seite: Sektion // Community (Rolle, Starboard-Kanal + Schwellwert, Screenshot-Kanal)
