feat(types): extend FileSystemHandle and optimize imports for consistency

- Added `getFile` method to `FileSystemHandle` interface for enhanced TypeScript compatibility with File System Access API.
- Improved maintainability by reformatting and aligning imports in `brainyData.ts`.
- Standardized spacing and indentation across structured comments and interface fields.

Purpose: Improve TypeScript support for file system operations and enhance code readability with consistent formatting and import management.
