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. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01CPrAGBxBT6GfPXzeWQ4AXb
