Console Split Sessions

What it was. The Code tab's split: "hold Cmd/Ctrl and click a session to open it in a split pane" (Claude Code desktop), so two sessions' conversations are read at once.

Why deferred. The console already runs sessions in parallel, each with its state in the sessions tab and one click apart, with a notification when a hidden one needs attention (workflow comparison). A split is a second conversation panel and a second composer on a page whose world already takes the screen, and nothing yet shows two sessions being read together rather than switched between.

Revisit when: the workflow comparison's day in the console records switching back and forth between two sessions as a recurring cost.

Cheaper interim: the sessions tab, and a second browser tab on the same host.
