 - Auto-reply: require slash for control commands to avoid false triggers in normal text.
+- Auto-reply: add `/reasoning on|off` to expose model reasoning blocks (italic).
+- Auto-reply: place reasoning blocks before the final reply text when appended.
 - Auto-reply: flag error payloads and improve Bun socket error messaging. Thanks @emanuelst for PR #331.
