Remove the entire /friend desktop companion feature (Tauri frontend, FriendService,
SSE/STT server, skills, tools, routes) and the 11G Tauri build artifacts. Migrate the
edgeTts helper from friend/tts.ts into services/voice/edgeTTS.ts so auto-TTS survives.
Remove local whisper STT (whisperSTT.ts + whisper_server.py/transcribe.py) and the
doubao + anthropic voice_stream backends, since STT now runs exclusively on Groq
Whisper (whisper-large-v3 / -turbo). Shared STT connection types move into groqSTT.ts
and the voiceProvider setting is narrowed to ['groq'] with a default. Also rework
edgeTTS.ts to use the node-edge-tts package instead of a Python subprocess, dropping
the now-unused scripts/speak.py.
