Implement selective HMR for changed files only

[virtualzx-nad]

Original issue from vitejs/vite vitejs#19538

Implement a configuration option to prevent full page reload during HMR and only reload the changed files. This is a complex feature that requires careful consideration of module dependencies and state management.

Required implementation:

1. Add new configuration option for selective HMR
2. Implement dependency graph tracking
3. Add logic to determine minimal reload scope
4. Handle edge cases like circular dependencies
5. Add comprehensive tests
6. Document the feature and its limitations

Considerations:

• Module boundary detection
• State preservation
• Performance impact
• Edge cases handling

This is an advanced task that requires deep understanding of Vite's HMR system.
