Readable names: CamelCase product names and words with numbers stay readable

The production dry run of releases:readable flagged 5.37M of 19.8M rows,
and its first sample held real names: "CrossStitcher - Issue 440",
"SchiffsModell", "FastFilms 2.04", "BestCrypt NP v4.0", "SmithsWork",
"Laura15Juli2026". Two CamelCase words with few vowels have four runs and
no lone letter: a scramble now needs five runs, a lone letter or an inner
capital run besides its few vowels; the consonant-run clause is gone
(it counted y); a token whose letter runs are all words or acronyms with
numbers between them is neutral. On a 49k-row production sample the
flagged share went from 27.4% to 26.4% with the letters-only flags all
scrambles; the evaluation sets are unchanged (LOG.md (129)).
