/**
* OmniRoute — Co-locate the LLMLingua-2 runtime into the raw Next standalone build.
*
* WHY: `npm run build` produces `.build/next/standalone/` and THIS machine's PM2
* deployment runs `server.js` from that directory directly (not the assembled
* `dist/` bundle). The standalone trace:
* - does NOT bundle `open-sse/services/compression/engines/llmlingua/onnxWorker.js`
* (dynamically spawned via worker_threads — untraceable by webpack), and
* - does NOT include the optional SLM deps (`@atjsh/llmlingua-2`,
* `@tensorflow/tfjs`, `js-tiktoken`) — they are optionalDependencies and are
* only installed at the ROOT `node_modules`.
*
* Result: after every plain `npm run build`, the LLMLingua engine silently
* fail-opens (text returned unchanged, no error) because the worker's runtime
* anchors (`process.cwd()` = the standalone dir) find neither the worker file
* nor the deps. This script re-applies both, mirroring what prepublish.ts +
* colocateOptionals.mjs do for the `dist/` bundle.
*
* Idempotent + fail-soft: skips quietly when the optional deps are absent at the
* root (the common slim-install case) and never throws into the build.
*
* Run manually after a build, or automatically via the `postbuild` npm hook.
