fix: use ?worker&url import so Vite compiles the worklet TypeScript

new URL('./file.ts', import.meta.url) copies the file verbatim — the
browser gets raw TypeScript and addModule() throws DOMException. Using
?worker&url tells Vite to bundle and compile the file, producing a .js
output that the browser can actually execute.
