OSC52 copy? (copy over ssh)

[SuperKenVery]

We currently rely on some external programs to copy text, which may or may not work, given the user can be under X/Wayland/SSH: https://github.com/kamiyaa/joshuto/blob/1f045515eafc83aa5214c72774bdbbc6500723f3/src/commands/file_ops.rs#L144-L158

Maybe consider using OSC52? It's should work everywhere, regardless of the environment.
