/**
 * Emits Azure code model with optional customization callback.
 *
 * This function applies Azure-specific defaults (generator name, license, decorators, etc.),
 * generates the metadata.json file, and delegates to the base emitter's `emitCodeModel`.
 * Downstream emitters (e.g., management plane) can call this instead of `$onEmit` to pass
 * an `updateCodeModel` callback for additional code model transformations.
 *
 * @param context - The emit context
 * @param updateCodeModel - Optional callback to modify the code model before emission
 * @returns A tuple containing void and any diagnostics generated during emission
