Agent session name not visible while attached

Description

When attached to a Claude Code agent session (via Agent View or background jobs), the session name is not displayed anywhere in the UI. You must detach/exit to identify which agent session you're in.

Steps to reproduce

1. Launch multiple background agent sessions with distinct names
2. Attach to one of them from Agent View
3. While inside the attached session, look for the session name — it's not visible anywhere
4. Detach — now you can see the session name in the agent list

Expected behavior

The agent session name should be visible while attached (e.g., in the status bar at bottom-right, or in the terminal title). This is especially important when running multiple agents in parallel.

Current behavior

No session name indicator while inside an agent session. The only way to know which agent you're attached to is to exit and check the list.

Why it matters

When running 2-3 agents in parallel on different tasks, switching between them without knowing which is which forces unnecessary detach/reattach cycles. A simple label in the status bar would solve this.

Additional context

The implicit recap on session resume is a great addition — showing the session name while attached would complement it perfectly.
