+ * Bun preload plugin: mock Vite-specific ?worker&url imports.
+ *
+ * Vite transforms `import Url from "./foo.ts?worker&url"` into a URL string
+ * at build time. Bun's test runner doesn't understand this suffix. This plugin
+ * intercepts any import ending in `?worker&url` and returns a dummy string,
+ * so modules that import worker URLs can load in tests without crashing.
+ *
+ * The Worker constructor will receive the dummy string and fail, which is
+ * expected — getWorker() catches the error and returns null, falling back
+ * to lezer-only highlighting in tests.
