[FEATURE] Agent sidebar panel in VS Code extension (like Cursor)

Problem Statement

I run 3-5 agents in parallel on the extension. Mix of coding tasks and knowledge work.

Thing is, every tab shows the same Claude logo.

No way to tell what's running, done, or idle without clicking into each one.

Tabs pile up horizontally and I'm constantly scrolling left and right just to find the right one.

There's no single place to glance at and see the state of all my work.

Basically the current tab-based UX doesn't scale for parallel workflows at all.

Proposed Solution

A small sidebar panel on the right side.

Cursor already does this and it works great - small, takes up little space, high info density.

What it should show:

1. Status per agent - running, done, idle
2. Preview of what the agent is currently doing
3. Time since last activity
4. Agent title/name with ability to rename
5. One-click to jump into any agent
6. Archive a. Move completed agents to a collapsible "Archived" section b. Keeps the active list clean but I can still go back to them
