Desktop Code tab: sidebar label "Ungrouped" should say "Ungrouped sessions"

In the Claude desktop app's Code tab, sessions that aren't in a group appear in the sidebar under a section labeled "Ungrouped".

**"Ungrouped" on its own tells the user nothing. Ungrouped what?** That's the key question, and the label never answers it. It names a state without ever naming the thing. As a user, I had to ask what these items were even called (sessions? tasks? projects?).

Suggestion: Say what the items are. Label the section "Ungrouped sessions", or simply "Sessions", so the sidebar uses the same term as the rest of the product.

Why it matters: Making new users guess what the sidebar contains adds friction for nothing. Saying "sessions" once in the UI would clear it up.

Environment: Claude desktop app on macOS (Apple Silicon).
