REVIEWING.md: house-style table carries the 2026-10-02 rulings

Parentheses are full-width throughout, a half-width space separates
Japanese from Latin words and inline code, and figure labels stay in
English until the engine supports a Japanese font. Register,
punctuation (now with the ，。 option) and code comments remain open
on QuantEcon/action-translation#337.

 If you think a house-style rule is itself wrong, say so on the pull request: it is then settled once for every lecture that follows, rather than lecture by lecture.
