Interactive workflow popup, like the file popup

[dnviti]

Problem / Motivation

Workflows (multi-step, multi-agent orchestrations) are currently shown the same way as any other agent delegation: a single line in a list with a status badge. There's no dedicated, interactive view for a workflow while it runs, even though workflows involve multiple stages and multiple agents working together — this makes it hard to follow what's actually happening during a workflow run.

Goal

Let users open a workflow in an interactive popup — similar to the existing file popup — where they can watch its progress live and explore what happened, instead of relying only on a single status line.

Scope

• An interactive popup for viewing a workflow, consistent in feel and behavior with the existing file popup (e.g. movable/resizable, can be expanded to fill the screen).
• The popup shows the workflow's stages/phases and which agents are working within each one.
• Progress updates live while the workflow is running.
• The popup remains available to review after the workflow completes, showing what each stage/agent did.

Non-goals

• Redesigning how workflows are triggered or configured.
• Changing the existing file popup itself, beyond reusing its established interaction pattern.

Acceptance Criteria

• A workflow can be opened in a dedicated popup from wherever workflows are currently listed.
• The popup behaves consistently with the file popup (movable, resizable/expandable).
• The popup reflects the workflow's stage/phase structure and shows live progress as it runs.
• After a workflow finishes, its popup still shows the full history of stages and agent activity for review.

Open Questions

• Should the workflow popup support drilling into an individual agent within a stage using the same agent-detail view requested separately, or should it show a lighter-weight summary per agent?
