v0.22.4 — Live resumes in chat + chat results overflow fix

Fixed

• "Live" sessions now resume in the chat — picking a running local
  session from the ⇄ Live menu opened it in the terminal (CLI panel); it
  now replays the transcript and continues in the chat window (switching
  to the chat layout if needed), like the Resume button.
• Chat results horizontal overflow — wide content (code blocks, long
  URLs, tables) no longer forces the message area wider than its
  container; messages get min-width:0 and code blocks scroll inside
  the bubble (fixes layout glitches on window resize).
