feat: Supersonic evaluator, Cactus Kev hash, repo split cleanup

Evaluator overhaul:
- Add Supersonic LUT trie evaluator (32M-entry, O(n) hand evaluation)
- Add Cactus Kev perfect-hash 5-card evaluator (prime-product hashing)
- 3-tier evaluation priority: Supersonic → Cactus Kev → Algorithmic
- DashMap-cached 7-card evaluation for lock-free concurrent access
- Rewrite JumpTable around CactusKevEvaluator + DashMap cache

Bot framework:
- Add StrategyBot adapter (Strategy trait → HoldemPlayer)
- Add register_bot_type() for plugin-style bot registration
- Add strategy module with modular composable strategies

Repository split:
- Remove holdem_bots from workspace (moved to private super_marvin repo)
- Remove holdem_bots dependency from holdem_sim
- Update cash_game.toml to use built-in bots only
- Clean up .gitignore (remove stale holdem_bots exclusion)
- Delete plans/ directory (internal planning artifacts)

Documentation:
- Add ARCHITECTURE_SUPERSONIC_EVALUATOR.md
- Add REFERENCES.md
- Update ROADMAP.md and VISION.md
- Remove outdated docs (ACHIEVEMENTS, RAKE, TOURNAMENT_RAKE, meerkat-alignment)

 # Poker AI Testbed & Live Server Roadmap
 
-## Step-by-Step Implementation Plan
-
-### Phase 1: Foundation
-
-**Basic poker engine**
-- Game state management
-- Game Info and Player Info traits
-- Event reporting and action scheme
-- Basic game rules (NL/FL/PL)
-
-**Configuration system**
-- TOML configuration structures
-- Bot parameter configuration
-- Game type configurations (Cash/SNG/MTT, buyins, blinds, hands per level, etc.)
-- Simulation parameters (hands/tournaments count, buyin thresholds for bots, etc.)
-
-### Phase 2: Simulation Testbed ✅
-**Goal:** Mass simulation capability
-
-**Testbed core** ✅
-- Tournament/cash game runners ✅
-- Result collection and analysis ✅
-- Bot interface with early folding capability ✅
-- Bot performance metrics & summary ✅
-- Simulation and game factories ✅
-- Configuration-driven experiment runner ✅
-- Seed control for reproducibility ✅
+## Phase 2: Simulation Testbed ✅
 
 **Remaining for mass simulation**
 - Parallel simulation engine (multi-threading)
 - Result visualization (charts/graphs)
-- Rebuy/addon support for tournaments
+- GUI for configuration of simulations and bots

-### Phase 3: Bot Framework
+## Phase 4: Bot Framework
 **Goal:** All bot types with playability enhancement
 
-**Bot core implementations** (partially complete — basic bots exist)
-- ~~Generic helper functions for strategies~~ (basic bots done: CallBot, FoldBot, RaiseBot, RandomBot)
-- Modular Strategy per stage and game situation
-- Rule-based bot with configurable thresholds – port from Java
-- Nash equilibrium calculator for SNG endgame – port from Java
-- Statistical tracking bot – port from Java
+**Bot core implementations** (partially complete)
 - Logging of decision-making process
 
 **Advanced bots**
+- Nash equilibrium calculator for SNG endgame – port from Java
+- Statistical tracking bot – port from Java
 - GPU acceleration for mass rollouts
 - Hand-reading opponent modeling (possibly with GPU integration)
 - Flop playability precomputation & score integration
 - Basic reinforcement learning skeleton
 - Hybrid bot combining multiple approaches
-- Factory for bot and sub-strategy composition
 - Genetic algorithm for bot evolution (via configuration files)
