screen clone should not make full requested height "written"
...
Previously, the screen clone would incidentally mark the full height as
"written" which would cause resize to create scrollback because it was
trying to preserve prior rows. A clone should not "write" any data. This
modifies the clone operation to create a screen with the correct height
but only copy data actually written.

terminal: check OSC parser for tmux 112 sequences from HN
...
Saw this on HN:
https://github.com/darrenstarr/VtNetCore/pull/14
I wanted to see if ghostty was vulnerable to it (it is not). But, its a
good example of a weird edge case in the wild and I wanted to make sure
it was redundantly tested. It looks like we read the "spec" (blog posts,
man pages, source of other terminal using tools, etc.) right.

zero-width chars are ignored if they're at col 0
...
This can cause a crash, and is impossible since zero-width chars are
always attached to a prior character. Word-wrapping doesn't come into
play here because this check happens prior to the wrapping.

OSC 52: Clipboard Control ( #52 )

This adds support for OSC 52 -- applications can read/write the clipboard. Due to the security risk of this, the default configuration allows for writing but _not reading_. This is configurable using two new settings: `clipboard-read` and `clipboard-write` (both booleans).
