+//! V4 full-duplex notification protocol for out-of-process plugins.
+//!
+//! V4 keeps the existing V3 request/response vocabulary but multiplexes
+//! requests, responses, and best-effort notifications over a single local
+//! socket. The V3 files (`src/ipc/{protocol,client,server}.rs`) are left
+//! untouched; all V4 logic lives in this module.
