the soulseek counterpart of the youtube drain — finally makes the people/airing
scans pay off. two automations (Auto-Download Movie / Episode Wishlist, hourly):
for each wished+released item, do a bounded blocking slskd search, pick the top
ACCEPTED release per the quality profile, and enqueue it exactly like a manual
grab (same add_video_download shape → the monitor finishes + organises it).
same standard as youtube: processes the WHOLE eligible wishlist (no total cap)
but searches a few at a time (max_concurrent, default 3, via a thread pool). a
busy guard skips the next hourly tick while a drain is still working. movies gate
on status='wanted' (skips monitored); episodes are all-wished. items already
downloading are skipped. quiet skip if the library folder isn't set.
reuses the real infra (build_query/slskd_search/_evaluate_hits/start_download/
download_monitor) — pure pick/select/record seam-tested; db queries added. 377
automation+video tests green.
