feat: add rake, bankroll management, seat randomization, FlockBot & ChumpBot

Browse source 
- Add RakeConfig with percentage-based rake and per-pot cap
- Add bankroll tracking (reset per hand or auto-refill threshold)
- Add seat randomization with seeded RNG for reproducibility
- Add FlockBot (tight-aggressive) and ChumpBot (loose-passive) bots
- Refactor HandRunner: extract finalize_result, compute_chip_movements, credit_winnings
- Add num_raises to GameInfo for authoritative raise counting
- Record SB/BB as Raise actions (Meerkat convention)
- Update all existing bot tests for new GameInfo fields
- Add ARCHITECTURE_RAKE_BANKROLL_SEATS.md documentation
