4.4.3

Fixed

• HTTP/2: a response that signals end of stream with a trailing HEADERS frame (trailers, or an empty trailing HEADERS as proxies emit for responses without a content-length) no longer hangs the body read until recv_timeout. The trailer event is now treated as end of stream, so reads complete on fresh and reused connections (#884).
• HTTP/2: sync reads run under a per-stream recv_timeout watchdog, so a lost frame fails fast with {error, timeout} instead of blocking until the connection dies.
• HTTP/1.1: a pooled connection that received unsolicited data while idle is dropped at checkout instead of having the bytes discarded, which could strand or corrupt the next read. Healthy idle connections still reuse normally, preserving keep-alive and the issue #544 stale-connection detection.
