Realm v0.2.0

• Space icons can be generated or uploaded, from a per-profile icon library reusable by every space under it.
• Thinking blocks render as Markdown, so an agent's headings, lists and code fences stop reading as literal syntax.
• AskUserQuestion gets a question card with the actual choices, rather than an Allow / Deny gate over a JSON blob. The chosen labels persist, so a replayed transcript records what was answered.
• Image attachments show a thumbnail in the transcript instead of only a filename.
• An unstarted session can be moved to another space from the sidebar, re-homing its environment and tearing down any terminal rooted at the old working directory.
• The composer's send key is configurable: Enter, or ⌘/Ctrl+Enter to free plain Enter for newlines.
• The notifications list reads as hairline-separated rows rather than a stack of background pills.

Fixed

Streaming ids were retired on an interim assistant notification, which can arrive per completed content block. A thinking block followed by text therefore splintered every remaining delta onto its own id.
