Provider credentials are bootstrap config and never reach the database
(DESIGN.md §10), so which providers exist is settled once at startup;
which of them a search runs is the `providers_enabled` row the API reads
per request. OpenSubtitles.com cannot be called without a registered API
key, so without one it is not offered at all.

Transmission has no route to Prowlarr, and Prowlarr redirects a
.torrent link to a magnet that a file fetch cannot follow. arr fetches
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.
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
