Rabbitty Beta 0.1.0-beta.48

The sidebar is now built on workspaces: add one with ⌘⇧O, close it from its header, and jump with ⌘1–9. Tabs that don't belong to any workspace collect in a Scratch section, and a shell that cd's out of its workspace re-files there automatically.

Sessions moved up into the top bar — one chip per tab with a breathing status dot, scrolling instead of shrinking when they overflow. Each workspace row in the sidebar shows live agent counts by state (running / idle / needs approval) and the git picture at a glance (+N −N, ahead/behind).

The browser pane remembers its open/close per workspace — and a browser an agent opens in a background worktree waits until you switch there. ⌘⇧L in a worktree now opens with the thread's original ask, verbatim.
