Frank 337afac91e fix(media): a TV plan that follows the authorities it was given
A dry run of the TV planner against the real 58k-file library produced a root
series called "01 NCOP" out of a bonus subfolder, copied Jellyfin's stale
numbering (every file under SNL 16-20/Season 16..19 carries season 16 episode
20; one Gundam row says season 2004), and lost subtitles a scene pack had
buried in Subs/<release-name>/.

- Folders now RESOLVE a series and never invent one: a folder's words match a
  registered name as a token run ("(CBB) Tengen Toppa Gurren Lagann - The
  Complete Series (BD 1080p)" names Tengen Toppa Gurren Lagann), and folder
  words alone name nothing, so an unknown pack's bonus folder parks instead of
  opening a new show at the library root.
- Numbering priority: the marker the file's own name states, then the Season NN
  folder plus the number the name leads with inside it, then the provider row.
  A row that still insists on season 1989 parks its file rather than creating
  Season 1989.
- The provider row keeps identity: the registered name and its year survive a
  file whose own marker numbers it, and the pack index a release leads with
  ("4a. Seed DESTINY") is folded out of the folder name.
- A sidecar searches every ancestor folder for the video it names, not just the
  parent, so Subs/<release-name>/<release>.jpn.srt follows its episode.
- The shared bonus-folder test no longer reads an index as a title: name_words
  drops "extras" as release junk, so "01. Extras" reduced to "01" and matched
  the "01" of "NCOP 01", cancelling the bonus evidence. Only words can name a
  film.

r"""The fleet's release-filename title parser: the grouping authority the relayout
plan uses for every file the media server never matched.
report: media-titles.py report [--probed TSV] [--out TSV]
the similar-copies census (DUP / REVIEW / EP-DUP groups) over the
ffprobe census scripts/media-census.py writes.
parse: media-titles.py parse NAME [NAME…]
what title_of() makes of a name — the way to check a naming accident
before it merges two films into one folder.
scripts/media-plan.py imports this file; over there the paths are arguments.
Method — three independent signals, so a naming accident cannot merge two films:
* franchise KEY : first two significant title tokens. Stable across parts of a
collection ("resident evil", "jump street") but NOT film-specific — it only
selects candidates.
* DURATION : the identity check. Same master encodes differ by at most a
couple of seconds; different films / cuts do not collide.
* SIZE SPREAD + YEAR: decide the tier. Two files same size AND same duration
are byte-twins (the hash pass confirms); same duration but different sizes are
two different releases of one film (deletable redundancy).
TV episodes (SxxEyy in the name) are grouped separately: their uniform runtime
would otherwise collapse a whole series into one "duplicate" group.
