Compilation Warnings

Non-Blocking Warnings (38 total)

All warnings are code quality issues (unused variables, dead code) and do not affect functionality:

1. Unused imports (2): microstructure::*, statistical::* in common/src/features/mod.rs
2. Dead code (6): Unused struct fields in EMA, ADX, SimulatedBar
3. Unused variables (18): Test setup variables (e.g., _adaptive, _rng, _i)
4. Unused assignments (5): cusum_s_plus, cusum_s_minus in regime orchestrator
5. Missing Debug impls (7): Suggested for feature extractors and regime detectors

Impact: None. These are linting suggestions for code quality improvements.

Fix Estimate: 15-30 minutes via cargo fix --lib -p ml and manual cleanup.
