balls 0.5.13

//! `bl-delivery` — the §11 delivery / worktree plugin binary (direct variant).
//!
//! A thin process edge over [`balls::delivery_bin`], the way `bl-tracker` sits
//! over [`balls::tracker::run`]: `main` reads the environment once at the
//! boundary — `$BALLS_PLUGIN_NAME`, the XDG bases, the working directory (the
//! bl-bfa8 rule: the library takes them as arguments) — and hands argv, stdin
//! and stdout to the library entrypoint, which owns the whole boundary
//! adaptation (`protocol`, the §7 wire, the §11 surfacing, the error voice).
//! A linking host multiplexing the plugin calls the same entrypoint, so there
//! is exactly one copy of the boundary.
