libc::EWOULDBLOCK is unix-only (kigi-shell links libc behind cfg(unix)); the v0.1.3 windows-msvc release build failed on it. fs2 exposes lock_contended_error() precisely as the cross-platform classifier (EWOULDBLOCK on unix, ERROR_LOCK_VIOLATION on Windows) — use it instead of the raw errno. No behavior change on unix; graph_project lock tests green.
