fix: improve VS Code config toggle handling with async state management

- Add loading state to prevent race conditions during config operations
- Convert effect-based approach to direct async handler for better control
- Support both writing and removing VS Code config through toggle
- Disable checkbox during async operations to prevent multiple requests
