[BUG] CTRL+Z will brick your claude code instance #194

Bug Description

Pressing CTRL+Z while in terminal mode on a running claude code window places it into a background state:

Claude Code has been suspended. Run `fg` to bring Claude Code back.
Note: ctrl + z now suspends Claude Code, ctrl + _ undoes input.

After this, no amount of stopping, closing, restarting seems to get it back. You basically have to exit vim and start it again as far as I can tell.

To Reproduce

See above

Expected Behavior

Suspend vim entirely as if you were in any other window, rather than suspending the nested instance.

Environment

• Neovim version: 0.11.5
• Claude Code CLI version: 2.1.45
• OS: rocky linux
• Plugin version: aa9a5

Error Messages

N/A

Additional Context

This works for me as a workaround:

    vim.api.nvim_create_autocmd("TermOpen", {
      callback = function(ev)
        local buf_name = vim.api.nvim_buf_get_name(ev.buf)
        if buf_name:match("claude") then
          vim.keymap.set("t", "<C-z>", "<cmd>suspend<CR>", {
            buffer = ev.buf,
            desc = "Suspend Vim from Claude terminal",
          })
        end
      end,
    })
