[FEATURE REQUEST] Add script/eval js in CLI with fetch

[kelvinauta]

I think it would be very useful when making fetch to a site, you could load a custom script.
That way you can create quick automations without needing to open a whole process with Puppetter or Playwright.
For example, I would like to add a script simply to scroll so that the content keeps loading...

I can suggest something like
lightpanda fetch <url> (--script <file> | --eval <javascript/text>)

This is a really nice idea. Being able to inject a small script during fetch would cover a lot of lightweight automation use cases (like scrolling, triggering lazy loads, etc.) without the overhead of Puppeteer/Playwright.
