+/**
+ * Worker-side RPC host — runs inside the child process spawned by the host.
+ *
+ * This module is the worker-side counterpart to the server's
+ * `PluginWorkerManager`. It:
+ *
+ * 1. Reads newline-delimited JSON-RPC 2.0 requests from **stdin**
+ * 2. Dispatches them to the appropriate plugin handler (events, jobs, tools, …)
+ * 3. Writes JSON-RPC 2.0 responses back on **stdout**
+ * 4. Provides a concrete `PluginContext` whose SDK client methods (e.g.
+ *    `ctx.state.get()`, `ctx.events.emit()`) send JSON-RPC requests to the
+ *    host on stdout and await responses on stdin.
+ *
+ * ## Message flow
+ *
+ * ```
+ * Host (parent)                          Worker (this module)
+ *   |                                        |
+ *   |--- request(initialize) ------------->  |  → calls plugin.setup(ctx)
+ *   |<-- response(ok:true) ----------------  |
+ *   |                                        |
+ *   |--- notification(onEvent) ----------->  |  → dispatches to registered handler
+ *   |                                        |
+ *   |<-- request(state.get) ---------------  |  ← SDK client call from plugin code
+ *   |--- response(result) ---------------->  |
+ *   |                                        |
+ *   |--- request(shutdown) --------------->  |  → calls plugin.onShutdown()
+ *   |<-- response(void) ------------------  |
+ *   |                                        (process exits)
