Rebuild: a poster's constant tag no longer makes one release of all their uploads

Release 145637 held four albums: the poster puts '[KiLL.dA.FuCkIn.
EaStErRaBbIt]----' before every upload, and the text outside the quotes
(when it names a release) was the key with the poster. The same made
one release of a poster's albums under '(PowBeertje80 Posted)' (a post
id, with the same [i/M]), of masterposts' films, and of one volume of
every set in a DVD9 post.

Now, when the file's stem describes something itself (12+ letters and
digits, two words of 3+ letters) and the text outside the quotes shares
no word with it (4+ letters as part of the stem, 3-letter words and
numbers whole; boilerplate like www/net/posted not counted; no 5+ digit
per-post id), that text is taken for the poster's tag and the stem
says which release the file is. Albums of track files ('FTA … Ketchup'),
'DIE_ZEIT_35' with '35_China_dl', 'FTD769997' posts, scene names with
abbreviated file names ('grp-sm') and generic sidecars ('file_id.diz')
keep their grouping.

releases:regroup re-keys a sample of the catalog with the current rule:
on homelab's test data 145637 → 4 albums, 111566 → 17 albums of 27
files, the rest of the subject releases that change mostly lose an ad
image ('Flyer-download-2-Day.gif'); stem releases unchanged. Ported to
edge-bench-rs: check.ts still finds all captures identical (ath 2013:
16 → 76 releases on both sides).
