Support dropping files to the terminal on OSX optionally to use quoted strings, instead of escapes.

[oderwat]

As a NuShell user i run into the problem that drag & drop of a file - for example from Finder - into Ghostty will result in something like /Users/anon/text\ file \(1\).txt.

This is not supported with NuShell and it would be very helpfull if such a drop action would result in "/Users/anon/text file (1).txt" instead.

I think this could be helpful in other cases too. For example when pasting into Helix I also get the same escapes.

I imagine that one could define the default paste mode between "escaped" "double-quotes" "single-quotes" "raw"?

Maybe it is also possible to have the mode change with different key modifiers, like "shift drop" means "quote escaped".
