/**
 * Bun build plugin: parakeet.js's bare `onnxruntime-web` import resolves to
 * `src/worker/ortShim.ts` (= Transformers.js's `onnxruntime-web/webgpu`), so
 * the inference worker bundles exactly one onnxruntime (D-051). Used by the
 * production build (scripts/build.ts) and the dev server's worker bundle
 * (src/index.ts). Without it the bundle carries parakeet.js's own 1.24.1
 * copy as well — never executed, but ~0.5 MB of dead weight and a CDN
 * wasmPaths default.
