Research direction

Start with the stack trace and inspect src/neovim/neovim.ts around syncVSCodeToVim, especially the nvim_buf_set_lines call at line 133. Review how the buffer is selected and synchronized, then reproduce the reported key handling scenario and verify that synchronization no longer raises the non-modifiable-buffer error.
