demo: love-humanity knob (funny alignment demo)

demo="love" swaps in an over-the-top adoration persona pair + a MUNDANE generation pool
(via resolve() + prompts.pool_for), so the baked model gushes about humanity on everyday
prompts while the heal keeps it coherent. demo="authority" (default) is unchanged.

- config: demo knob + LOVE_POS/LOVE_NEG preset.
- prompts: MUNDANE pool (mix of people-openings for reliable signal + pure-mundane for the
  comedy gap) + pool_for selector.
- steering: generate_steered/generate_plain pull pool_for(cfg.demo).
- scripts/judge_love.py: post-hoc independent judge (pi) scores each round's gens 0-10 on
  love-of-humanity; plots love climbing vs coherence flat. Smoke-tested.

+"""Post-hoc love judge for the demo run (demo=love).
+
+Reads a run's events.jsonl adapter_gen records (the per-round baked-model generations on the
+MUNDANE pool), scores each one 0-10 on unhinged-love-of-humanity with an INDEPENDENT judge
+(pi, default google model -- not the loving model itself, so not circular), and plots the
+mean love-score against tinymfv coherence over rounds.
+
+The story we want: love-score climbs while coherence (p_any_ans) stays flat = "we aligned it
+to love humanity harder each round and it stayed sane". Qualitative twin = report.html.
