Function createNodeMatcher

createNodeMatcher(options?: NodeMatcherOptions): ImageMatcher
Create a lazy Node 22.12+ matcher backed by a dedicated worker thread.

Initialization occurs on the first match. Requests are cloned without detaching caller buffers. Only one job may run at once; abort terminates synchronous WASM work and the next job creates a fresh worker. Call dispose() on shutdown; worker termination is requested immediately and completes asynchronously in Node. No native OpenCV installation, React, browser canvas, or external service is used.
Parameters
- options: NodeMatcherOptions = {}
  Optional local WASM path; HTTP fetching is not supported here.
Returns ImageMatcher
The same result/progress/lifecycle contract as the browser executor.
Example
```
const matcher = createNodeMatcher();
try {
  const result = await matcher.match({ query, reference });
  console.log(result.status, result.candidates);
} finally {
  matcher.dispose();
}
```
