Complete migration to vertical slice architecture with TanStack Query + Radix

This completes the project refactoring with no backwards compatibility, making the migration fully complete as requested. ## Core Architecture Changes - Migrated all types from centralized src/types/ to feature-based architecture - Completed vertical slice organization with projects/tasks/documents hierarchy - Full TanStack Query integration across all data operations - Radix UI primitives integrated throughout feature components ## Type Safety & Error Handling (Alpha Principles) - Eliminated all unsafe 'any' types with proper TypeScript unions - Added comprehensive error boundaries with detailed error context - Implemented detailed error logging with variable context following alpha principles - Added optimistic updates with proper rollback patterns across all mutations ## Smart Data Management - Created smart polling system that respects page visibility/focus state - Optimized query invalidation strategy to prevent cascade invalidations - Added proper JSONB type unions for database fields (ProjectPRD, ProjectDocs, etc.) - Fixed task ordering with integer precision to avoid float precision issues ## Files Changed - Moved src/types/project.ts → src/features/projects/types/ - Updated all 60+ files with new import paths and type references - Added FeatureErrorBoundary.tsx for granular error handling - Created useSmartPolling.ts hook for intelligent polling behavior - Added comprehensive task ordering utilities with proper limits - Removed deprecated utility files (debounce.ts, taskOrdering.ts) ## Breaking Changes (No Backwards Compatibility) - Removed centralized types directory completely - Changed TaskPriority from "urgent" to "critical" - All components now use feature-scoped types and hooks - Full migration to TanStack Query patterns with no legacy fallbacks Fixes all critical issues from code review and completes the refactoring milestone.
