v2.22.3

A patch release: nothing the model reads changes.

• A reused keep-alive connection now takes each request's own timeout. It
  kept the timeout of the request that opened it, so a non-streamed model
  call made after the 5 s end-of-turn prewarm or the 3 s backend ping was
  cut off at 5 or 3 s and reported as "backend unreachable: timed out". Of
  the 237 recorded eval runs marked invalid for a timeout, 206 ended at 3 or
  5 s and 2 at the real 300 s limit, so most of the "platform" invalid runs
  on record were this. The interactive REPL streams replies over another
  path and was not affected; the eval runner and use_streaming: false were.
