fix(scripts): port-census must not call prose words facts

A hyphen or a trailing period inside a word was enough to make it a tracked
token, so `long-standing`, `deployed:` and `cleaned.` were reported as lost
facts while real identifiers hid behind them. Require a digit, dot, slash,
colon, `--`, two hyphens (`frank-tts-engine`) or ALL-CAPS in the stripped
word. The census of the log rewrite went from 979 noisy lines to a set whose
unheld tokens are all fact-shaped.
