- Fix TypeScript errors in migration service, router, and platform services
- Add electronAPI type declarations for Electron platform
- Remove type checking from development builds for faster hot reload
- Update tsconfig.node.json to resolve configuration conflicts
- Ensure type safety for production while maintaining fast development workflow
