Added distinct timeout diagnostics for websocket receive starvation
versus local relay backpressure, preserving the existing timeout,
counter and reconnect threshold policy.
> `git diff HEAD~1..HEAD -- piker/data/_web_bs.py`
Track whether proxy_msgs() is awaiting ws.get_message() or
snd.send(). Report that phase, URL, configured deadline, timeout
count and reset threshold for every timeout, before the existing
threshold/reset diagnostic. Capture the configured deadline once
per operation so the report matches the deadline that elapsed.
> `git diff HEAD~1..HEAD -- tests/test_websocket.py`
Two real loopback variants use a silent server versus one payload
and an unconsumed zero-capacity Trio relay. Require the appropriate
phase and URL on the actual first timeout. All 15 selected
Binance/websocket cases pass. No live provider was contacted.
Read-only tracing found a permissive invalid-venue path: get_mkt_info
accepts USDM via its usd substring check and preserves that venue
in MktPair, whereas Client.bars() indexes canonical USDTM pair keys.
This identifies a potential late failed-startup path, not proof of
the corrected-chart stall or of leaked producer ownership.
