v0.1.711

Add addressed UDP send and receive to the shared C/LLVM native socket runtime through sock_sendto and sock_recvfrom. Numeric IPv4/IPv6 sender metadata, binary and empty packets, flags, arena bounds and thread-local errno are covered by the loopback gate. A zero-capacity receive without sender metadata reports EAGAIN; queued packets retain their sender.

Reduce C Map storage when replacing a list with its existing tail, and size a compacted map's first arena block to its live entries. Deterministic capacity checks reject controls that restore either former allocation policy. The Map suffix fixture also checks a copied snapshot across replacement and compaction.

Update the code-generation guide, tutorial and collection example to describe implemented backends and concrete builtin factory values. Retain phase tables as implementation history, use the maintained Wasm host runner, and document the existing C compaction boundary for uncopied reads on the running stack.

Validation includes 2,946 tests, 248 parity programs, all 188 required CI gates, native UDP checks, and Map capacity and sanitizer checks. Distribution binaries are built for macOS arm64 and Linux x86_64; the Linux binary is checked on stock Ubuntu 24.04 and 26.04.
