"""Regression test: bare /hatch must not call raw input() off the main thread.

Slash commands dispatch from the process_loop daemon thread while
prompt_toolkit owns stdin. The old code called ``input()`` directly, which
rendered nothing and silently swallowed subsequent keystrokes until Ctrl+C
(found in the Aug 2026 full-surface CLI QA sweep). The handler must route
through the thread-aware ``_prompt_text_input`` helper, which cancels
cleanly (returns None) when prompting isn't safe.
