[Bug] Text input lag and garbled output when switching between Claude Code and Neovim

Bug Description
After updating to the latest v2.0.32, in general text input in nvim is slow. Likely this is because inputs are processed in claude-code when I'm switching from it. This occurs as well when I press shortcut keys.

Related issue #10735 #10375

Then, after I return to claude-code by exiting nvim, sometimes there are some garbled text that's likely coming from nvim.

How to reproduce

• Setup nvim + LazyVim (just use the most basic settings: https://www.lazyvim.org/installation)
• Use ctrl+g shortcut to edit prompt using claude-code

I'm using nvim + LazyVim
