Added built-in push-to-talk / toggle microphone voice control to the OpenCode Electron desktop app for Windows (and other desktop platforms). Speech is transcribed with cloud STT providers (Deepgram streaming, Groq Whisper, OpenAI Whisper). Short spoken phrases can be interpreted as voice commands.
### Architecture
- **Main process** (`packages/desktop/src/main/voice/`): recording orchestration, SoX/FFmpeg capture when available, cloud STT providers, global hotkey (`Alt+Space` by default), IPC + electron-store config.
- **Renderer fallback capture**: when SoX/FFmpeg is not installed, the renderer uses `getUserMedia`, downsamples to 16 kHz mono PCM, and streams chunks to the main process.
- Committed voice control source changes on `dev` as `feat(desktop): add voice control` (`78bf9a35eb50e183128a003ce8ef3a5c8b6bb359`).
- Added remote `cloudaxe` → `https://repo.cloudaxe.io/CloudAxe/cloudaxe-opencode.git`; left GitHub `origin` unchanged.
- Direct full-history HTTP push hit server `413 Request Entity Too Large`; seeded history via Gitea migrate from `anomalyco/opencode`, then force-with-lease updated `cloudaxe/dev` to the local voice tip.
- Verified `cloudaxe/dev` SHA matches local `dev` (`78bf9a35eb50e183128a003ce8ef3a5c8b6bb359`).
