+ * Package's js/index.js reads COMPUTER_USE_INPUT_NODE_PATH (baked by
+ * build-with-plugins.ts on darwin targets, unset otherwise — falls through to
+ * the node_modules prebuilds/ path).
+ *
+ * The package exports a discriminated union on `isSupported` — narrowed here
+ * once so callers get the bare `ComputerUseInputAPI` without re-checking.
+ *
+ * key()/keys() dispatch enigo work onto DispatchQueue.main via
+ * dispatch2::run_on_main, then block a tokio worker on a channel. Under
+ * Electron (CFRunLoop drains the main queue) this works; under libuv
+ * (Node/bun) the main queue never drains and the promise hangs. The executor
+ * calls these inside drainRunLoop().
