Improve XHTTP transfer reliability under slow destinations and resource pressure with bounded packet pipelining, admission before body reads, queue-acceptance acknowledgements, and cancellation-safe session handling. Preserve reusable H1 uploads, correct H2/H3 finalization, add configurable receive windows and download-tail timeouts, validate effective request capacity, and expand Xray/Mihomo interoperability coverage with pinned peers in CI.
Adds Xray-compatible XHTTP/SplitHTTP with packet-up, stream-up, and stream-one modes over HTTP/1.1, HTTP/2, and HTTP/3, including REALITY and existing proxy chains. Bounded buffering, flow-control-aware admission, connection pooling, and inactivity-based timeouts maintain backpressure without imposing a minimum upload rate. Preserves TLS key-exchange and ML-DSA policies, adds configuration examples and interoperability coverage, and vendors an h3 fix to prevent empty DATA frames from truncating streams.
