feat: Phase 0c - migrate correlation_metrics to data_layer/correlations (11 functions)
All checks were successful
Deploy Development / deploy (push) Successful in 44s
Build Test / lint-backend (push) Successful in 0s
Build Test / build-frontend (push) Successful in 12s

- Created NEW data_layer/correlations.py with all 11 correlation functions
- Functions: Lag correlation (main + 3 helpers: energy/weight, protein/LBM, load/vitals)
- Functions: Sleep-recovery correlation
- Functions: Plateau detection (main + 3 detectors: weight, strength, endurance)
- Functions: Top drivers analysis
- Functions: Correlation confidence helper
- Updated data_layer/__init__.py to import correlations module and export 5 main functions
- Refactored placeholder_resolver.py to import correlations from data_layer (as correlation_metrics alias)
- Removed ALL imports from calculations/ module in placeholder_resolver.py

Module 6/6 complete. ALL calculations migrated to data_layer!
Phase 0c Multi-Layer Architecture COMPLETE.

"""
Correlation Metrics Data Layer
Provides structured correlation analysis and plateau detection functions.
Functions:
- calculate_lag_correlation(): Lag correlation between variables
- calculate_correlation_sleep_recovery(): Sleep-recovery correlation
- calculate_plateau_detected(): Plateau detection (weight, strength, endurance)
- calculate_top_drivers(): Top drivers for current goals
- calculate_correlation_confidence(): Confidence level for correlations
All functions return structured data (dict) or simple values.
Use placeholder_resolver.py for formatted strings for AI.
