   Implemented on next. napi_call_threadsafe_function comes from Hermes' first-party Node-API (API/napi/hermes_napi_tsfn.cpp, adopted in #372), and #398 supplies the post_task hook that carries the queued calls to the JS thread via the runtime's CallInvoker (packages/host/cpp/HermesNapiHost.cpp).

   Verified by packages/node-addon-examples/tests/threadsafe-function, a port of Node's test_threadsafe_function — it exercises both blocking and non-blocking calls, queue-size limits, and the re-post path when Hermes' per-tick dispatch budget is exhausted.
