(cherry picked from commit 5655ea4)

* feat: add configurable maxPayloadSize for WebSocket (#4955)

(cherry picked from commit bd91f86)


* test: fix flaky permessage-deflate limit timeout (#5229)

(cherry picked from commit 9d82667)


* fix(websocket): enforce max payload size across fragments

Account for previously received fragment bytes when checking WebSocket payload size limits, so fragmented messages cannot exceed maxPayloadSize by splitting the payload across frames.

Add coverage for cumulative fragmented payload size enforcement.


(cherry picked from commit b4c287b)


* websocket: handle empty fragments and stream limits

Treat zero-byte frames as real fragments so fragmented messages can start
with an empty frame and empty continuations still count toward
maxFragments.

Pass dispatcher WebSocket limits through to WebSocketStream's parser, add
regression coverage for WebSocket and WebSocketStream fragment limits, make
the fragment close tests wait for both endpoints, and fix the Client docs
typo for maxFragments.


(cherry picked from commit c5ed787)
