+ * Loader for the bundled `@livekit/local-inference` native binding.
+ *
+ * Memory model (measured ~138 MB for the EOT model, ~2 MB for VAD): Node has
+ * no forkserver/COW, so anything loaded in a job worker is private to that
+ * worker. To avoid paying ~138 MB per worker, the EOT model is NOT loaded in
+ * job workers — it runs in the shared `InferenceProcExecutor` (see
+ * `inference/eot/runner.ts`), loaded once per host. The VAD stays in-process
+ * (it's small and runs continuously) and is reached via this loader.
+ *
+ * There are intentionally no public `prewarm*` helpers: EOT auto-warms via
+ * the inference runner's `initialize()` at proc startup, and the VAD lazy-
+ * loads on first stream.
