Daemon::spawn_with_env for extra child environment, database_path()
and media_root() accessors so a test can seed a media file directly,
the daemon built with translate-command, and the plausible/farfetched
Podnapisi zip fixtures the subtitle tests download from.
Eleven empty crates per DESIGN.md §11, versions and lints pinned once in the
root manifest, Justfile carrying the §12 gate, nix dev shell.
The frontend steps in `just ci` no-op until web/ exists. arr-core carries one
placeholder test because `cargo nextest` fails a zero-test run, and relaxing
that would let a broken filter go green later.
Closes#1
