Roman 4e1faf4cd9 Ohm comme client de téléchargement Sonarr (API compatible qBittorrent)
- /api/v2/* : login SID (mot de passe = clé Torznab), app/version,
  torrents/info (progression temps réel), properties (content_path),
  add (rejoue le grab encodé dans le .torrent de service, dédupliqué
  par infohash SHA-1), delete (± fichiers), pause/resume
- Les grabs Sonarr sont marqués « sonarr:<hash>| » dans source_key →
  suivis de bout en bout : Sonarr importe, renomme et range les épisodes
  dans sa bibliothèque, puis retire le torrent de la file Ohm
- L'indexeur Torznab embarque les paramètres du grab dans l'announce
- README : nouveau mode « client de téléchargement » recommandé (Remote
  Path Mapping documenté), blackhole en variante minimale
- 3 nouveaux tests (flux complet add → suivi → import → delete)

"""API compatible qBittorrent Web API v2 — Ohm comme client de téléchargement Sonarr.
Sonarr sait piloter un qBittorrent ; Ohm implémente le sous-set suffisant pour
être vu comme un client de téléchargement « torrent » :
- login (`/auth/login`, mot de passe = clé API Torznab) + session SID
- `torrents/add` : Sonarr renvoie le .torrent de service servi par l'indexeur
Torznab → le grab est rejoué (dédupliqué par infohash) dans la file interne
- `torrents/info` / `properties` : progression temps réel, `content_path`
pointant vers le fichier dans /downloads (mapper en chemin hôte côté Sonarr
via « Remote Path Mapping » si besoin)
- `torrents/delete` : retrait de la file, avec ou sans le fichier
- `pause`/`resume` : branchés sur le gestionnaire de téléchargements
