Tighten AI insight bullet constraints further — still truncating at 800 tokens

Browse source 
Live-tested again: 800 tokens still wasn't enough for Sonnet's bullet density
(6 dense bullets, cut off mid-sentence again). Capped bullet count to 4-5,
added a hard 35-word single-sentence limit per bullet, told it not to add a
closing summary, and raised the cap to 1200 for genuine headroom.
