Readable names: a token-by-token classifier for the readable flag

Searches with the readable filter on returned scrambles: with a random
4-letter query nearly every hit was one ("Zx5AjNaK-mh7CFg6Hf8uu",
"Description - Lt5nHjlo3RiuBb3C", "PsNdnYiugfZ", "bd5b...-addon"), and
15% of a 6,000-row sample of the catalog's readable names were. looksRandom
knows single-token shapes only; separators, spaces, a random "extension"
of any length and a packaging word hid the rest.

isUnreadableName (lib/release/readable.ts) and names::is_unreadable_name
read a name token by token: words (one case or Capitalized), scrambles
(letter/digit and case switches, lone letters between capitals, inner
capital runs, few vowels, hex) and neutral tokens (digits, codes like
S02E10 and 1080p, CamelCase, packaging words); a name is unreadable when
its scrambles outweigh its words. Scene tags' "i" for "I" and the
NZBSPLIT hash are read as such. On the evaluation sets: 554 of 559
random-search names caught, 0 of 630 real names flagged (LOG.md (129)).

The edge's readable flag and the prober's inner names use it; the drop
rules keep looksRandom, which is narrower. An unnamed release goes to the
pending store (decision f), so more of the obfuscated groups' releases
wait for a probe now. releases:readable clears the flag on the existing
catalog's rows by name (a dry run by default).
