Add comprehensive offline synchronization support for habits and entries: ## Infrastructure (Phase 1) - Add UpdatedAt and DeletedAt timestamps to Habit and HabitEntry entities - Implement soft delete with Delete(), Touch(), and IsDeleted() methods - Create SQL migration with optimized composite indexes for sync queries - Add GetChangesSince() and SoftDelete() to both repositories - Update all Find* methods to exclude soft-deleted records - 13 comprehensive TDD tests for sync repository methods ## HTTP Endpoints (Phase 2) - GET /api/v1/sync/changes: retrieve all changes since timestamp - POST /api/v1/sync/batch: apply client changes with conflict resolution - Implement Last-Write-Wins strategy using UpdatedAt timestamps - Add authentication and rate limiting (100 req/min) - Validate user ownership for all sync operations - 9 tests for sync handlers (3 queries + 6 commands) ## Technical Details - Composite indexes: (user_id, updated_at) for optimal query performance - No pagination: atomic sync operations for data consistency - Upsert behavior: create resources if not found on server - DTOs with full entity state including timestamps - Swagger documentation updated for new endpoints All 220+ tests passing ✓
