Complete P2 (LLM) and P3 (voice pipeline) implementation

P2 — homeai-llm:
- Fix ollama launchd plist path for Apple Silicon (/opt/homebrew/bin/ollama)
- Add Modelfiles for local GGUF models: llama3.3:70b, qwen3:32b, codestral:22b
  (registered via `ollama create` — no re-download needed)

P3 — homeai-voice:
- Wyoming STT: wyoming-faster-whisper, large-v3 model, port 10300
- Wyoming TTS: custom Kokoro ONNX server (wyoming_kokoro_server.py), port 10301
  Voice af_heart; models at ~/models/kokoro/
- Wake word: openWakeWord daemon (hey_jarvis), notifies OpenClaw at /wake
- launchd plists for all three services + load-all-launchd.sh helper
- Smoke test: wyoming/test-pipeline.sh — 3/3 passing

HA Wyoming integration pending manual UI config (STT 10.0.0.200:10300,
TTS 10.0.0.200:10301).
