feat(runtime/coach,persona): death post-mortem coach + Russian chat narration
Coach (runtime/coach/postmortem.js):
- bot.on('death') → captures context (last skill, hostile, recent
scenarios, journal nearby, snapshot) → inserts row into knowledge.deaths
- Periodic drain (every 5min, ≤3 Pi calls/hour, 12min cooldown):
batches up to 8 unanalysed deaths, asks Pi to extract 1-3 generalised
lessons in JSON, persists to knowledge.lessons + knowledge.postmortems
- Pi prompt asks for structured advice (trigger_skill, trigger_hostile,
avoid_skill, prefer_skill, confidence) so future dispatch can act on it
Persona (runtime/persona/chatter.js):
- Polls snapshot every 5s, narrates Russian lines on transitions:
skill start, threat spotted, dusk/dawn, respawn, stuck, milestone done
- Rate-limited: min 75s gap, max 8/hour, duplicate suppression
- ~14 template buckets covering gather/craft/build/travel/combat/weather
Wire-up in bot.js (5 lines):
- initKnowledge({stateDir}) fire-and-forget at module load
- attachCoach + attachChatter inside bot.once("spawn")
Tests: 14 new (7 coach, 7 persona). Total suite 230 green.
