"""Tests for Ctrl+G external-editor submit in the classic CLI.

Ctrl+G opens the current draft in ``$EDITOR``; on a clean save the draft is
submitted (TUI parity) rather than left in the input area. Submission in the
CLI is driven by the custom Enter keybinding, not the buffer accept_handler,
so ``_open_external_editor`` chains a done-callback that calls
``_submit_editor_buffer``. These exercise that submit helper directly.
