feat(ml): WAVE 29 DQN Codebase Cleanup & Refactoring Campaign

BREAKING CHANGES: - Removed orphaned dqn.rs monolithic trainer (4,975 lines) - Removed orphaned dqn_ensemble.rs module (816 lines) - Removed orphaned tft.rs and tft_complete_int8_integration_test.rs - TFT trainer split into modular directory structure DQN Module Refactoring: - Split trainers/dqn.rs into modular structure (config.rs, statistics.rs, trainer.rs) - Fixed hyperopt 39D search space (continuous params only) - Boolean flags (use_dueling, use_double_dqn, use_per, use_noisy_nets) are now FIXED architectural decisions - use_distributional defaults to false (Candle BUG #36 - scatter_add gradient issues) Clean Module Structure: - ml/src/trainers/dqn/ directory with proper mod.rs exports - ml/src/trainers/tft/ directory with config.rs, types.rs, model.rs, trainer.rs, tests.rs - All P0 features validated: TD-error clamping, batch diversity, LR scheduler, priority staleness Documentation: - Added comprehensive docs in docs/codebase-cleanup/ - ADR-001 for DQN refactoring decisions - Rainbow DQN component matrix and quick reference guides Build Status: Compiles with zero errors 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

+# DQN Hyperopt Redeployment WITH CHECKPOINT SAVING FIX
+# Generated: 2025-11-02
+#
+# CONTEXT:
+# - Previous run: dqn_hyperopt_optimized_20251102_220747 (NO CHECKPOINTS SAVED)
+# - Root cause: No-op checkpoint callbacks in ml/src/hyperopt/adapters/dqn.rs
+# - Fix: Agents 1-3 replaced no-op callbacks with safetensors save logic
+# - This run: Will save .safetensors files for all 50 trials
+#
+# STRATEGY:
+# - Hybrid approach with 5-minute validation gate
+# - Early abort if checkpoints still not saving (saves $0.09 of $0.11 budget)
+# - Real-time monitoring with S3 checkpoint verification
+# - Post-completion validation with model loadability tests
+#
+# COST/TIME ESTIMATES:
+# - Success: 36 min, $0.11 (same as before, but WITH checkpoints)
+# - Early abort: 9 min, $0.02 (saves $0.09 if fix is broken)
+# - Expected value: $0.096 (85% success probability)
