Idle agent shows spinning indicator, looks like it's still working

Bug

When the main agent is idle and waiting for user input, the activity indicator continues to animate/spin. This makes it look like the agent is still thinking or processing when it's actually done.

Expected behavior

When the agent is finished and waiting for input, the indicator should be solid/static (not spinning), matching the behavior of completed subagents. Completed subagents show a solid indicator with a duration like "2m 27s" — it's clear they're done. The main agent should look the same when idle.

Actual behavior

The main agent's indicator keeps spinning/animating even when it has nothing to do. There's no visual distinction between "actively thinking" and "waiting for user input."

Why this matters

• Users can't tell if the agent is done or still working
• Creates confusion about whether to wait or start typing
• Completed subagents above show a clear "done" state (solid indicator) while the main agent below looks like it's still churning
