feat: add integration test framework and health check improvements

- Add test helper library with assertion functions (scripts/lib/test-helpers.sh)
- Add gateway integration test script (scripts/tests/gateway-test.sh)
- Add configuration validation tool (scripts/validate-config.ts)
- Add health-check.ts library with Tauri command wrappers
- Add HealthStatusIndicator component to ConnectionStatus.tsx
- Add E2E test specs for memory, settings, and team collaboration
- Update ZCLAW-DEEP-ANALYSIS.md to reflect actual project state

Key improvements:
- Store architecture now properly documented as migrated
- Tauri backend shown as 85-90% complete
- Component integration status clarified
