wip: Sicherungs-Commit aller Änderungen seit April + Arbeitsstruktur (CLAUDE.md, ROADMAP.md, PROGRESS.md, Autopilot)

6 Wochen uncommittete Arbeit (Voice-Channels, LiveKit-Manager, Settings-Modal u.v.m.)
als ein WIP-Commit gesichert, damit nichts verloren geht und der Pi den aktuellen
Stand klonen kann. Thematische Aufarbeitung: siehe ROADMAP M0.
