Setting buffer.tempfile = 'prompt.md' pushed prompt_toolkit into its complex-tempfile path, which creates a temp dir and then calls os.makedirs() on that same path when no subdirectory is present. That raises EEXIST before the editor can launch. Keep prompt_toolkit on the simple tempfile path with .md suffix, and make the editor fallback chain explicit on both surfaces: $VISUAL -> $EDITOR -> nvim -> vim -> vi -> nano.

* 1. $VISUAL / $EDITOR (user's explicit choice)
|
|
* 2. first executable found on $PATH from `nvim` → `vim` → `vi` → `nano`
|
|
* 3. literal `'vi'` so spawnSync still has something to try

* Mirrors the override on `input_area.buffer._open_file_in_editor` in cli.py
|
|
* — both surfaces should pick the same editor so the CLI/TUI handoff
|
|
* doesn't surprise the user with nano in one and vim in the other.
