E11 error when ModeChanged autocmd triggers in command-line window

[DanRioDev]

Description

When a task is queued for terminal creation and the user is in the command-line window (q:, q/, etc.), the ModeChanged autocmd triggers and attempts to call nvim_open_win, which throws E11: Invalid in command-line window.

Error Message

Error in ModeChanged Autocommands for "*:n":
Lua callback: ...ocal/share/nvim/lazy/overseer.nvim/lua/overseer/util.lua:633: E11: Invalid in command-line window; <CR> executes, CTRL-C quits
stack traceback:
        [C]: in function 'nvim_open_win'
        ...ocal/share/nvim/lazy/overseer.nvim/lua/overseer/util.lua:633: in function 'run_in_fullscreen_win'
        ...im/lazy/overseer.nvim/lua/overseer/strategy/jobstart.lua:130: in function '_create_terminal'
        ...im/lazy/overseer.nvim/lua/overseer/strategy/jobstart.lua:103: in function <...im/lazy/overseer.nvim/lua/overseer/strategy/jobstart.lua:98>

Root Cause

The can_create_terminal() function in lua/overseer/strategy/jobstart.lua (lines 91-94) checks:

• vim.api.nvim_get_mode().mode == "n"
• not util.is_floating_win(0)

However, the command-line window reports mode as "n" (normal), but has special restrictions where nvim_open_win is not allowed.

Reproduction Steps

1. Run an overseer task that creates a terminal
2. While the task is pending, open the command-line window with q: or q/
3. Exit the command-line window (which triggers ModeChanged *:n)
4. Error occurs

Suggested Fix

Add a check for the command-line window in can_create_terminal():

local function can_create_terminal()
  return vim.api.nvim_get_mode().mode == "n" 
    and not util.is_floating_win(0) 
    and vim.fn.getcmdwintype() == ""
end

vim.fn.getcmdwintype() returns an empty string when not in the command-line window, and a non-empty string (like :, /, or ?) when inside it.
