feat(platform): improve cross-platform compatibility with Windows support

Enhance application to work seamlessly across operating systems by implementing platform-specific adaptations:

- Update node-pty to version 1.1.0-beta34 for Windows support
- Implement PowerShell terminal support for Windows environments
- Integrate cross-spawn library for reliable process execution on all platforms
- Standardize development ports to industry defaults (3001/5173)
- Add dynamic shell detection based on operating system

BREAKING CHANGE: Development server ports have been changed from 3008/3009 to 3001/5173 to align with standard Vite/Express defaults
