nzbget, qbittorrent: full nox downloader modules (ADR 0044/0046)

nzbget (usenet, JSON-RPC) and qbittorrent (torrents, WebUI API with manual SID
session). Tools: status, queue/torrents, add, pause/resume, delete. Both poll
and emit module.<app>.download.added and module.<app>.download.completed — the
key plex consumes to rescan; completion is keyed off real success (nzbget
history SUCCESS, qbittorrent progress reaching 1), not mere queue disappearance,
so a failed or deleted item is not reported as done. Typecheck; manifests parse.
