Function isSafari

isSafari(nativeOnly?: boolean): boolean
Checks if the current browser is Safari.

Note: On iOS, all browsers (Chrome, Firefox, Edge, etc.) are required by Apple to use WebKit (Safari's engine), so they behave similarly to Safari.
Parameters
- nativeOnly: boolean = true
  If true (default), only returns true for native Safari. If false, includes all iOS browsers that use WebKit (Chrome iOS, Firefox iOS, etc.).
Returns boolean
True if the browser is Safari (or WebKit-based on iOS if nativeOnly is false), false otherwise
Example
```
import { isSafari } from '@consumidor-positivo/ts-utils';

if (isSafari()) {
  console.log('Running on native Safari');
}

// Include all WebKit-based browsers on iOS (Chrome, Firefox, etc.)
if (isSafari(false)) {
  console.log('Running on Safari or any iOS browser (all use WebKit)');
}
```
