fix: retry polling on HTTP/2 GOAWAY connection errors

APITimeoutError is a subclass of APIConnectionError, so the previous
except clauses caught timeouts but not bare APIConnectionError, which
is what httpx raises when an HTTP/2 GOAWAY frame drops the connection
mid-poll. Catch APIConnectionError instead so GOAWAY-interrupted polls
continue retrying rather than surfacing as APIConnectionError to callers.
