v0.2.0-rc.3: pillar-up escape + advice everywhere + danger POI

Closes the gap rc.2 left open. Live observation showed:
- Pi-coach extracted 5 high-quality lessons (do not explore.far at
  night near zombies, etc.) but none of them fired (applied_count=0
  across the board). Root cause: dispatcher consulted advice only on
  the main curriculum path; the bot was falling into the wander/
  explore.far FALLBACK after each gather attempt bailed, which
  bypassed consult().
- Bot was wedged in a pit on (608, 90) with stone walls. recovery.
  tunnel-out kept failing ("Digging aborted") because mining stone
  with fists takes ~10s/block; pathfinder watchdog kills it.

This patch:

1. survive.pillar-up (runtime/skills/pillar-up.js) — new escape skill.
   Places a placeable block under the bot and jumps onto it; repeats
   up to 8 steps. No pickaxe required. Works in dirt/cobble/planks/
   sand/gravel/wool/etc. The bot's vertical exit from any pit it can
   stand in.

2. Wedged-emergency reflex (runtime/reflex.js). At the top of
   curriculumReflex, if noProgressReason is wedged-like AND position
   hasn't shifted ≥16 blocks in 60s AND no hostile in 6m AND pillar
   block in inventory → dispatch survive.pillar-up. 2-min cooldown
   between attempts.

3. consult() now also runs on the WANDER/explore.far fallback path
   (runtime/reflex.js curriculumReflex). Pi-coach lessons can finally
   take effect. If the fallback skill is overridden to a non-eligible
   skill but the bot has a placeable block, falls back to pillar-up.
   Outcomes feed reportAdviceOutcome so confidence stays grounded.

4. recordPOI("danger") on death (runtime/coach/postmortem.js). Spatial
   memory now flags where the bot died, expires after 6h. POI table
   was empty in rc.2.

5. SAFE_OVERRIDES extended (runtime/coach/advice.js): adds
   survive.pillar-up and village.choose-base so coach lessons can
   route there.

Tests: 255/255 green (+9 pillar-up).
