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.

poker_rituals table + log_ritual/list_rituals/set_alligator/alligator_active;
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.
