/**
 * ONNX - Public facade for `@runanywhere/web-onnx`.
 *
 * Loads `racommons-onnx-sherpa.{js,wasm}` (the dedicated ONNX/Sherpa
 * Emscripten module) and registers the ONNX runtime + Sherpa speech
 * vtables with the C++ plugin registry. After `ONNX.register()` resolves,
 * STT/TTS/VAD operations flow entirely through the proto-byte adapters
 * in `@runanywhere/web` core into that WASM module.
 *
 * Usage:
 *   ```ts
 *   import { RunAnywhere } from '@runanywhere/web';
 *   import { ONNX } from '@runanywhere/web-onnx';
 *
 *   await RunAnywhere.initialize();
 *   await ONNX.register();
 *   const vad = await RunAnywhere.detectVoiceActivity(silence);
 *   ```
