docs: ML inference production cleanup implementation plan
8-task plan covering:
- Delete ~4,600 lines of dead code (push_metrics, legacy tests/benches)
- Remove MLFeatureExtractor from trading_agent_service
- Delete MLFeatureExtractor + SimpleDQNAdapter from ml_strategy.rs (~2,100 lines)
- Refactor SharedMLStrategy to new_with_models() constructor
- Update all callers (backtesting, integration tests)
- Create EnsembleModelAdapter + build_production_strategy() factory
- Harden metrics HTTP server (timeout, size limit, charset)
- Full verification
