/**
 * WebXRMesh component
 *
 * This component enables real-world mesh detection in WebXR AR sessions.
 * It detects and renders environmental geometry like walls, floors, and furniture.
 *
 * **Data Upload Modes:**
 * 1. **Auto-Update Mode** (when `autoUpdate: true`, default):
 *    - Automatically detects mesh changes (new/updated/removed)
 *    - Pushes updates to server only when changes occur
 *    - Event type: 'WEBXR_MESH_UPDATE'
 *    - Set `autoUpdate: false` to disable
 *
 * 2. **RPC Mode** (always active):
 *    - Server sends 'GET_WEBXR_MESH' request with matching key
 *    - Component responds with latest mesh data
 *    - Response event type: rtype from request or 'GET_WEBXR_MESH_RESPONSE'
 *
 * **Requirements:**
 * - WebXR session must be initialized with 'mesh-detection' feature
 * - Only works in immersive-ar mode
 * - Device must support mesh detection API
 *
