feat: VoiceCoach v2 — livekit-agents 1.5 personal voice assistant

Replaces pipecat 0.0.48 (6 manual patches, DuplicateIdentity reconnect storms)
with livekit-agents 1.5 SDK. New features:
- SvelteKit UI with live transcript, VAD ring, mode bar, vocal meter, history view
- SQLite session store with WAL mode (cross-session memory)
- Async SpeechBrain vocal/emotion analysis injected per turn
- Homelab tools: SSH/docker, Prometheus alerts, Home Assistant, SearXNG search
- OpenClaw LLM gateway preserved (qwen2.5:14b via Ollama)
- 4 modes: coaching, vent, practice, briefing
