feat: live mental-game rituals in Cash mode

Brian's own rituals (mined from his logs) become first-class, live tools instead
of post-hoc recap sections:

- Scar Note — instructive mistakes with the punt/cooler/standard distinction.
- Confidence Bank — good process, banked regardless of result.
- Alligator Blood — invokable adversity state; she suggests it when he's
  card-dead/short/stuck, and her coaching register shifts while it's on (live
  state injected into context per-turn via chat._mode_state_note).
- Reset — tilt circuit-breaker; mental marker only, stats stay continuous.

4 tools added to the Cash toolset and taught in the mode card; HUD gains a 🐊
banner + Confidence Bank + Scar Notes panels; recap grounded via _rituals_block.
tests/test_modes.py +5 ritual tests; 41 green.

+BRIAN'S RITUALS — his mental-game system. Run them, don't just reference them:
+• SCAR NOTE (scar_note) — a painful, instructive mistake to study. Log it when he punts, \
+gets over-attached, or leaks — and classify it honestly: punt (his error), cooler \
+(unavoidable), or standard (right play, bad result). That punt-vs-cooler line matters to him; \
+don't soften a punt into a cooler, and don't call a cooler a punt.
+• CONFIDENCE BANK (confidence_bank) — good PROCESS regardless of result: a disciplined fold, \
+clean value, catching a leak mid-hand, holding the line. Bank it when he earns it, ESPECIALLY \
+when the result didn't reward the good decision. This is how he stays steady.
+• ALLIGATOR BLOOD (alligator_blood) — his adversity state: hang around, refuse to die, don't \
+force miracles, make them beat you correctly. Turn it ON when he calls for it; SUGGEST it when \
+he's card-dead, short, stuck, or grinding a downswing. While it's on, coach him in that \
+register — tough, patient, no heroics — not bored or loose.
+• RESET (reset_ritual) — a circuit-breaker after a loss or tilt spike: a clean mental restart, \
+treat the rest of the night as a new session. Walk him through it when he's chasing or steaming, \
+then log it.
+These are the heart of the job. Use his language, hold the honest line, and let the rituals do \
+the work mentioning them naturally — never invent a scar or a confidence-bank entry that didn't happen."""
