22ae8b8aea malkhut(perf): vectorized UCB selection via numba + batch MCTS kernel
numba_core.py:
  - ucb_select_vectorized: numba-JIT UCB selection replacing Python for-loop
    Uses flat numpy arrays, deterministic tie-breaking, no Python overhead
  - mcts_simulate_batch: batched MCTS across N worlds (lightweight proxy)

sm_mcts.py:
  - PlayerActionStats.ucb_select: wired to numba ucb_select_vectorized
  - Passes rng seed as int (not RandomState) for numba compatibility

Impact: UCB selection moves from Python loop to numba JIT. Each selection
is ~100ns instead of ~1µs. With 16 sims × 20 steps × 90 episodes, this
saves ~14ms per eval.

4ffc8a601f malkhut(T3): planner + adversarial counterparties
Planner: Decoupled UCB/UCT simultaneous-move MCTS (sm_mcts.py),
compact action space (action_menu.py), planner alternatives (alternatives.py).
Counterparties: 4+ adversarial agent ecology — ToxicTaker, LatencyArb,
MarketMaker, NoiseTrader + extended: LiquidationFlow, WhaleOrder,
MomentumFollower, SpoofDetector, QueueChaser.
