Module libc/errno

libc/errno
Stability: unstable — a raw C binding, not a Yo design. The public surface over it is `std/sys/errors`, which maps these codes onto the `IoError` enum every `std/fs`, `std/net` and `std/process` result carries; `std/env` and `std/crypto/random` read individual codes (`EINTR`) directly. The VALUES are per-platform (that is the point of binding them rather than writing literals), and the LIST is additive-by-demand: entries appear as ports need them, so no completeness claim is made here. Reading `errno` after a call is only meaningful when the call reported failure, and only for the calling thread. Freezing would require deciding that `IoError` covers every code a supported OS can return, which it does not yet. — stable modules only change additively; this one may still change.
