Replaces the single-purpose PR diff right panel with a tabbed sidebar
that shows both the existing PR diff and real-time git repository
changes from the workspace agent.
There's an accompanying backend PR
[here](https://github.com/coder/coder/pull/22565).

## Backend surface
One endpoint drives this feature:
- **`WS /api/experimental/workspaceagents/{id}/git/watch`** —
bidirectional WebSocket. The client sends `refresh` messages; the agent
responds with `changes` messages containing per-repo branch and unified
diff. The workspace agent also automatically pushes changes as they
occur in the workspace.
Adds deprecation markers for MUI components and the custom Stack
component to guide migration to shadcn/ui and Tailwind CSS.
Changes:
- Added JSDoc @deprecated tags to Stack component and type definitions
- Added deprecation comments to MUI imports in theme files
- Expanded Biome noRestrictedImports rules to flag all MUI component
imports

I noticed we have been overusing colors in the UI, so simplifying is better for the "look and feel" and maintaining the styles over time.

If you want to have a better sense of what it looks like, I recommend you go to the Chromatic snapshot.
