 * In-memory `TypedIpcRegistry` impl —— Phase 2 不接真 Electron `ipcMain`，提
 * 供 main-process 同进程 `handle` / `on` / `send` / `invoke` 的 fake。
 *
 * - `handle` / `invoke` 与 `on` / `send` 是**独立 channel space**：send 只触
 *   发 on listener；invoke 只调 handle handler；同 channel 名互不影响。
 * - audience / validator option Phase 2 不强制，仅 accept；Phase 3 接 trusted
 *   sender set 时再实施。
