feat: add option: close_after_yank

[EmmetZ]

Could we have a close_after_yank setting in the default config? It would default to true but let users choose their preferred behaviour.

use case:
sometimes I want to copy multiple words and paste them in different places, but once I yank the first word, scrollback buffer automatically closes and I have to relaunch it again to yank the rest.

I get this idea from Alacritty since it won't quit vim mode after a yank operation. (Thanks for this awesome plugin. Now I can use vim mode in Kitty just like in Alacritty but with even more features!)

Do you think this is appropriate :) ?

@EmmetZ
This seems reasonable to me. Is your use case, you copy some text from the scrollback buffer and then past it in another window/program then come back and select different text?

I typically work in the same window so didn't think about this scenario with multiple yanks.

Sorry for the late reply.

Yes in my use case sometimes I need multiple yanks. For example when one command goes wrong and I don't know why. I need to copy the command and the error log and ask google or llm. But there might be other outputs which are useless between the command I enter on the command line and the actual error messages, in which case I need to multiple yanks.
