[FEATURE] Sub-agent visibility

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

When working with sub-agents, it's not clear what model they're running.

With Fable 5 orchestrating, orchestrator says it is launching Sonnet 5, but in the sub-agent session view it says "Fable 5" and the model switcher says "Active: Fable 5" but orchestrator says the API stamps say Sonnet 5.

Proposed Solution

Have the model of sub-agents clearly visible in the session and on the sub-agents list view in the main session.

i,e:

<sub-agent-name>: <model/effort level> - <task description>

Alternative Solutions

The only workaround appears to be checking the API logs

Additional Context

It's also not clear which type of agent system is being used; is it the legacy one or the TeamCreate one? We don't know.
