LLM: feed live combat state into character chat

buildStateTurn now takes a live snapshot (HP/%, in-combat, threat, kills, location) and
renders it as in-voice 'right now' lines — so asking a fighter mid-run gets answers aware
of their current wounds and the threat around them, not just persisted history. tiny.js
passes comboCtrl.getHero()+getThreat() via getLive when this hero is the one on the field.
