Task/subagent progress display no longer shows agent name (e.g. Explore, General)

[rcdailey]

Description

Since v1.2.16 (the new task/subagent progress design), the TUI no longer displays which agent type is being used for a task. Previously, you could tell at a glance whether a task was running an Explore, General, or custom agent. Now only the task description is shown.

Current output:

│ Task Verify Refit cancellation behavior
└ 22 toolcalls · 1m 1s

Expected output:

│ Explore: Task Verify Refit cancellation behavior
└ 22 toolcalls · 1m 1s

The title format should be [AGENT NAME]: [TASK DESCRIPTION], where the agent name is visually distinct (bold, colored, or both) so it stands out from the description.

This applies to both in-progress and completed task output. It likely affects custom agents as well.

I filed #16287 which extends this with session ID display alongside the agent name. I have a working concept locally with a screenshot on that issue.

My concept appends the info at the end -- Task Verify cancellation behavior [explore · ses_33e4d822fffe...] -- but I see you proposed a prefix style with the agent name visually distinct: Explore: Task Verify cancellation behavior. The prefix style probably reads better for agent identification at a glance. I'd also like to see a session ID or truncated version of it (even just the last 6 characters) -- I rely on session IDs for navigating subagent sessions in multi-agent workflows.

Combining both ideas, something like:

│ Explore: Task Verify cancellation behavior [d822ff]
  └ 22 toolcalls · 1m 1s

│ General: Task Find latest Next.js version [kFSmNS]

Happy to provide a PR that covers both -- open to suggestions on the visual format.
