Add --no-alternate-screen (-X) flag

[ev1lm0nk3y]

I was experiencing issues when moor was being used when interactive prompts were required by external cli tools.

• Implement --no-alternate-screen (alias -X) to disable switching to the alternate screen buffer.
• Refactor twin library to support screen options.
• Update public embedding API with NoAlternateScreen option.

This is a split from #417

Can you give an example of an external CLI tool that wants to control a pager?

How does git have problems with moor using the alternative screen?

I'm missing something here, I've been using moor as my git pager since 2013 and I've never had issues with that...

Ah, I misunderstood your question. While git is an external tool that outputs results to your screen, you wanted to know what tool used moor expecting input from a user during its execution.

I believe I was using the Linear or Notion CLI tool. It's been a few weeks at this point, but I seem to remember that I was asked to provide a token during its auth login flow but it depends on the pager to display results normally.

But if moor was still capturing keypresses, wouldn't that break any tool regardless of altscreen or not?

If you had a followable concrete example that would be super!
