RTCDataChannel.send behaves differently depending on the buffer it is handed: a heap buffer with an accessible backing array sends the entire backing array regardless of position and limit, a read only heap buffer honors the window, and a direct buffer sends the full capacity. Any caller that slices, flips, or reuses a buffer silently transmits the wrong bytes.
All paths now send exactly the bytes between position and limit, read through a duplicate so the caller's buffer state is untouched. Java only, no native changes.
