Rebuild: image sets, documents and audio albums as releases

Picture groups made a release per image: 501k single-file releases in
the first 24 ranges of the bottom 500 groups (a.b.models 385k), ~120M
for all of them. Counters written out ('File 027 of 132', '[12of42]',
'104 of 472', '[2239-6389]', '02/17', '0097-1574'; only when the first
number is at most the second, so '[1948-12]' stays) and per-file sizes
('76.88 MB', '335555 Bytes') kept every subject unique.

- subjectRemainder removes those counters and sizes, and empty brackets.
- A subject-named release is bounded by its counter's total
  (counterTotal: the first form found): uploads a poster names alike
  stay apart, an upload's files (par2, nfo) together.
- Images and audio tracks don't take the poster-tag rule: the subject
  names the set or album. An image set without a counter: the image's
  name up to its last number, without numbers.
- Documents and comics (pdf, epub, mobi, azw3, djvu, cbr, cbz, cb7, chm,
  lit, doc, docx) are a release each: collections post hundreds under
  one subject ('cw-horror&mystery').

releases:regroup --group re-keys a group's indexed releases together:
cheerleaders 55,741 -> 3,165 releases, models 385,298 -> 40,313, German
audiobooks 4,106 -> 1,724, playstation 3,309 -> 2,345; comics and
e-books a release per item; boneless unchanged. Ported to edge-bench-rs;
check.ts: identical on all captures.
