feat(phase-12-13): complete performance optimization and test coverage

Phase 12 - Performance Optimization:
- Add message-virtualization.ts with useVirtualizedMessages hook
- Implement MessageCache<T> LRU cache for rendered content
- Add createMessageBatcher for WebSocket message batching
- Add calculateVisibleRange and debounced scroll handlers
- Support for 10,000+ messages without performance degradation

Phase 13 - Test Coverage:
- Add workflowStore.test.ts (28 tests)
- Add configStore.test.ts (40 tests)
- Update general-settings.test.tsx to match current UI
- Total tests: 148 passing

Code Quality:
- TypeScript compilation passes
- All 148 tests pass
