Release 4.178.0

What's new reads like news (plan §9). shipped.js uses the tags Blog now writes on every change (kind: new, better, fixed, internal; areas; plain words) and the newest devblog Network's changelog proxy carries.

• The card (render): titled "What's new"; the newest devblog leads it with its picture, title and summary; each row shows its kind as a word tag and up to two area chips, in plain words with the commit subject as its title; internal changes count as housekeeping and stay out of the card, like pin bumps.
• The updates page (log): the same row; a second chip row filters by kind (All changes, New, Better, Fixed, and ?kind= in the address); internal work gathers at the end of its day in one fold that says how many ("3 housekeeping changes"); pin bumps keep their grouped row ("Shared 4.177.0 reached 41 sites").
• Without the tags (older entries), rows read as before.
