API to control whether raw mode, input, etc. are used on creation

Right now it's unconditional

I'm developing a CLI library using Mosaic. It works great, but when I run Mosaic in CI environments like GitHub Actions, I encounter the error "Cannot enter raw mode on a non-interactive terminal". We can work around this by setting an environment variable:

env:
  MOSAIC_RAW_MODE: false

Mosaic uses System.getenv to retrieve this variable, which prevents programmatic updates. Consequently, I'm forced to ask users to configure it manually(I would like to observe values in Compose). If we could switch to using System.getProperty(), we could modify it using setProperty. However, this is a Java-only API, so ideally, it would be beneficial to have a more platform-agnostic API for this. I'm hoping we can make suspend fun runMosaic(enterRawMode: Boolean, content: @Composable () -> Unit) public.

By CLI library do you mean a library that other CLI apps will consume? I'm curious what API surface you expose for rendering within a host application.

Sorry, "CLI library" was miss leading. It's a just a CLI tool. 
I was able to workaround this problem by using internal function.
