Production Migration Guide

This guide covers migrating from prototype/basic implementations to production-grade components with zero data loss. **New Features:** - ✅ Auto-reconnection with exponential backoff - ✅ Connection state management (enum-based) - ✅ Sensor calibration (remove bias/drift) - ✅ Data validation and sanitization - ✅ Performance metrics tracking - ✅ Quality indicators for readings - ✅ Comprehensive error handling **New Features:** - ✅ Connection retry logic with backoff - ✅ Adaptive FPS control (1-10 FPS based on latency) - ✅ Frame quality assessment (blur + brightness) - ✅ Batch optimization for API calls - ✅ State management (STOPPED, RUNNING, ERROR, etc.) - ✅ Performance metrics tracking **New Features:** - ✅ Atomic transaction-based saves - ✅ Database corruption detection & recovery - ✅ Template versioning system - ✅ Automatic backups (timestamped) - ✅ Data validation with physical plausibility checks - ✅ Cross-validation for accuracy measurement - ✅ Outlier detection and removal - ✅ Consistency scoring - ✅ Thread-safe operations - ✅ Template export/import **Breaking Changes:** - `SensorFeatures` now has `validate()` method - `GestureTemplate` has additional fields: `version`, `consistency_score`, etc. - Database now creates `backups/` subdirectory
