egui_inspection: cross-platform local socket via interprocess

Browse Source 
Replace std::os::unix::net::UnixStream in the InspectionPlugin with the
interprocess crate's local_socket::Stream, so the transport works on Windows
(named pipe) as well as unix/macOS (unix domain socket).

- New transport module (transport feature) with socket_name() and
  generate_socket_target() — one shared, platform-split place to build/allocate
  local-socket names, used by both ends of the connection.
- Drop the cfg(unix) gates on the plugin module; gate on the plugin feature only.
- attach() now takes a socket name string and connects via interprocess; the
  stream is split with Stream::split() instead of UnixStream::try_clone().
