fix: only run checktime if not in command line window

[tandetat]

The checktime command reloads buffers that changed on disk. It can't run inside the command-line window (q: / q/). When CursorHold or FocusGained fires while you're in that window, Neovim throws E11:

Error in CursorHold Autocommands for "*":
E11: Invalid in command-line window; <CR> executes, CTRL-C quits: checktime

Thanks for the fix! The getcmdwintype() guard is the right approach for avoiding E11.

One small thing: the indentation in the code snippet is slightly off — vim.o.autoread is at the top level but vim.api.nvim_create_autocmd is indented by 2 spaces. Since this is a standalone snippet, they should be at the same level:

vim.o.autoread = true
vim.api.nvim_create_autocmd(
  { "FocusGained", "BufEnter", "CursorHold" },
  {
    callback = function()
      if vim.fn.getcmdwintype() == "" then
        vim.cmd("checktime")
      end
    end,
  }
)

The markdown formatting cleanups look good too.

Fixed it, thanks!
