fix: cleanup repostiory, migrate to typescript, add refresh command

[dubisdev]

I just refactored callbacks into promises to make the code more readable.

Please, check if all this is working ok on MacOS and then we can release a new version 🚀

I'm not sure what the first :global element is doing in src/Preview/styles.module.css

Maybe it is just and old style that is no more used

@dubisdev mind sending me the npmjs org invitation again? Not sure I got it 🤔

[dubisdev]

Of course! I've just sent you a new one 🚀
