**feat(config): add support for 'DOM.Asynciterable' in TypeScript config files**

- Updated `tsconfig.unified.json`, `tsconfig.browser.json`, and `tsconfig.json` to include `"DOM.Asynciterable"` in the `lib` option.
- Ensured compatibility with asynchronous iteration patterns in DOM APIs.

**Purpose**: Enable support for DOM asynchronous iterable utilities, improving compatibility with modern TypeScript and DOM usage scenarios.
