- ReadFrame reads each frame into a reused per-conn buffer via NextReader
instead of letting ReadMessage allocate one per frame; ~41% fewer bytes on a
1MiB download. Safe: proto.Unmarshal copies the payload out and readLoop is
the sole reader.
- the data wire's websocket read is bounded by its own max message size (a full
frame + framing overhead), independent of the signalling message limit, so a
peer cannot OOM the server with an oversized frame even when signalling limits
are disabled. Drops the old coupling that clamped MaxFrameSize under the
signalling limit.
