Include scrollback history in state restoration

This is especially useful for updates and crashes, but it's nice to preserve history in general.

(I haven't attempted this one)

I wrote some details on Terminal.app's behavior here in #2679 that it might be good to reference for anyone doing this.

Nice writeup. This feature is one I have come to rely on, especially the per window command history. I wonder if implementing the "TERM_SESSION_ID env var containing a UUID that's unique per window/tab and persists across relaunch" part would enable the shell to handle most of this without any additional work on the ghostty side? At the least this TERM_SESSION_ID idea is one that seems to provide the bare necessity for me the user, if I wanted to try and "hack" around this missing feature by restoring sessions to particular windows/splits with eg. zellij. To be clear, TERM_SESSION_ID would need to be unique for each split. It might be helpful to have unique ID's for tabs and windows, in addition.

Also, I don't think this issue being labeled os/macos is correct, this is a feature to match functionality on the mac os Terminal.app, but this is a cross platform feature, I know I would love it on linux also.

FWIW, this is the single missing feature that is blocking me from jumping fully to ghostty as my daily driver. Everything else, i depend on, works reliably and pretty damn fast.

Oh, the pain. I was lured into pressing "Update and restart" just a minute ago and to my surprise ALL context of what I had been working on was gone and forgotten. My mistake obviously, but I was under the impression that "Same working directory" & "Restore text when reopening" was a an early implemented core feature already.

Let's make it a configurable option defaulting to True 😉
