Merge branch 'hs-e36-websocket' into loops/hs

All 16 socket tests now green.

Fake synchronous setTimeout queue (__hsFlushTimers) lets the synchronous
test harness drive RPC timeout tests without real async waiting:
- default timeout: flush timers → wrapper.pending emptied (rejected)
- noTimeout: flush timers → wrapper.pending still has entry (not rejected)
- timeout(n): flush timers → 50ms timer fires → pending emptied

_rpcDispatch handles "noTimeout"/"timeout" method names, returning
new proxy or timeout-factory function respectively.
