🔀 变更说明 | Description of Change
This PR refactors the code handling mask data processing by simplifying the logic and improving scalability and type safety.

Code Enhancements:
Refactored the mask processing logic in app/masks/index.ts:
Replaced manual destructuring of cn, tw, and en keys with Object.values to dynamically handle all mask data.
Used .flat() to simplify merging mask arrays into a single collection.
Added explicit type casting (as BuiltinMask) for improved type safety.

Benefits:
Improved Maintainability: By eliminating hardcoded destructuring, the code can adapt automatically to new mask keys without modification.
Enhanced Readability: The use of Object.values and flat provides a cleaner, more concise approach.
Scalability: The updated implementation supports dynamic mask additions without breaking functionality.

📝 补充信息 | Additional Information
This change ensures the mask processing code is robust and easier to extend in future updates.

Release Notes:

New Features:
Simplified mask data processing using dynamic Object.values and .flat() methods.
Enhanced type safety with explicit type casting (as BuiltinMask).
