avril-net

TCP and Unix stream transport primitives shared by avril's HTTP engine and raw networking bindings. This crate owns listener binding, accepted streams and peer addresses, and socket-file cleanup; callers enforce capability policy.

Linux Unix listeners use pinned directories, procfs-relative binding, and retained filesystem inodes. Other Unix platforms use path-based binding with best-effort identity-checked cleanup. Existing entries are never removed to make room for a listener. Non-Unix platforms report unsupported Unix operations.
