Mohamed Boudra 2a890208ce feat(app): show a subagent's parent and a way back to it (#7784)
A subagent pane now names its parent and takes you back to it. With a composer, a pill leads the rail above it; without one, a parent box takes the composer's place. Both open the parent through navigateToAgent.
