2.12.0

Added

• Show the current theme in the header. Click the theme label to open the
  searchable gallery; automatic selections also show an Auto indicator.
• Confirm theme changes with a visible connection-style notification near
  the prompt, preserving the draft and recording the result in Activity.

Fixed

• Keep the welcome headline, repository name, logo, header controls and
  prompt labels readable across dark and light themes.
• Use theme colors for success, warning and error notifications, and retain
  full prompt contrast while the agent is working.
• Keep Connect, Harness Hub and Exit accessible in narrow terminals by
  placing theme and session details on a second header row when needed.
• Respect sidebar navigation when a deferred startup callback requests
  composer focus.

Changed

• Use SuperQode as the default theme when no saved selection exists, while
  continuing to restore valid saved themes on startup.
