jgrusewski f5947c2b22 Wave 16S-V11: Bug #8 fix + P2-A/B implementation ...

Bug #8 (CRITICAL): Fixed action selection frequency catastrophe
- Root cause: execute_action called during training (522,713 orders/epoch)
- Fix: Removed execute_action from experience collection loop (line 928-936)
- Impact: 522,713 → 0 orders/epoch (100% reduction)
- Transaction costs: $338K → $0 (eliminated)
- Test suite: ml/tests/action_selection_frequency_test.rs (3/3 passing)

P2-A: Configurable Initial Capital
- CLI argument: --initial-capital (default: $100K, min: $1K)
- Files modified: trainers/dqn.rs, train_dqn.rs, hyperopt adapter
- Test suite: ml/tests/configurable_capital_test.rs (8/8 passing)
- Supports: Small accounts ($10K), Standard ($100K), Institutional ($500K+)

P2-B: Cash Reserve Requirement
- CLI argument: --cash-reserve-percent (default: 0%, range: 0-100%)
- Reserve enforcement: BUY trades only (SELL always allowed)
- Dynamic reserve adjusts with portfolio value
- Files modified: portfolio_tracker.rs (70 lines), trainers/dqn.rs, train_dqn.rs
- Test suite: ml/tests/cash_reserve_requirement_test.rs (10/10 passing)

Test Status: 21/21 core tests passing (P2-C deferred due to API mismatch)

- Agent #1: Bug #8 investigation (transaction cost analysis)
