VS Code Extension: Auto Add async/await Keywords

This VS Code extension automatically adds missing `async/await` keywords when you save a TypeScript file. A `tsconfig.json` file is required in your project folder. The extension intelligently adds `async` and `await` keywords to ensure asynchronous functions run correctly. To prevent `await` from being added to a specific asynchronous function, add the comment `// no-await` at the end of the function call. The first conversion might be slow, but subsequent conversions will be faster.
