Description: Patch release preventing large buffered HTTP/1 responses from truncating under downstream backpressure

## Highlights

- **Complete buffered responses under backpressure** — sync workers now honor partial `sendmsg()` results and resume at the exact unsent header or body offset.
- **Production-driven regression proof** — deterministic partial-write tests are paired with a real slow-reader socket transfer whose response exceeds the constrained kernel send buffer.

## Upgrade notes

- This is a backward-compatible patch release with no configuration migration.
- Applications serving large buffered HTTP/1 responses through a slow client or proxy should upgrade from 0.9.1.
- The normal full-write path keeps one `sendmsg()` call and the existing response buffers. The completion fallback runs only when the socket accepts a prefix.

## Fixed

- Prevent the sync worker from silently dropping the unsent suffix of a large buffered response when `socket.sendmsg()` returns a legal partial-write byte count. ([#312](https://github.com/lbliii/pounce/issues/312))
