Adds processes/ umbrella for repeatable acquisition workflows. First child
is subtitles/, with recipe README (executable by Claude Code), CHANGELOG,
per-show run logs, and a tested helper at lib/sub-fetch.sh.
Run on American Dad: S01 (7 eps) passed, S02-S04 (51 eps) broke. Library
uses Hulu/DSP season ordering; OpenSubtitles indexes by Fox airing order;
plugin queries by (parent_imdb_id, season, episode) so library S02E01
returns 0 hits. v2 design = direct OpenSubtitles REST with per-episode
imdb_id lookup; pending API-key registration.
