fix: enhance packem configuration with isolated declaration transformer and cjsInterop

- Added isolatedDeclarationTransformer to the packem configuration for better TypeScript support.
- Enabled cjsInterop to improve compatibility with CommonJS modules across multiple configurations.
- Updated legacyBrowsers and other browser lists to use 'as const' for better type inference in TypeScript.
