the link itself and sends Transmission a magnet or the torrent bytes.

Eleven empty crates per DESIGN.md §11, versions and lints pinned once in the
root manifest, Justfile carrying the §12 gate, nix dev shell.

placeholder test because `cargo nextest` fails a zero-test run, and relaxing
that would let a broken filter go green later.
