v0.1.1

Improvements

• The AI chat now renders Markdown more naturally, including readable headings,
  lists, inline code, and lightweight code blocks with copy actions.
• Image paths in AI replies can turn into image previews, and those previews can
  be added to the canvas, used as references, copied, revealed in Finder, or
  focused on the canvas when already present.
• The chat panel is easier to read with larger message and input text, plus a
  resizable width for longer replies.
• Canvas selection, snapping, resizing, and drag thresholds feel steadier when
  arranging images.
• Codex session handling is more resilient, including better active-turn
  steering, runtime discovery, and Windows image handling.
