Add a live Workspace + RunFrame Cosmos example for drop-in tscircuit.com integration

[rushabhcodes]

Summary

This PR adds a functional side-by-side WorkspaceCodeEditor + RunFrame Cosmos example that follows the same integration pattern used in tscircuit.com.

What changed

• added a live Cosmos fixture that wires workspace files into RunFrame via fsMap
• added a local SuspenseRunFrame helper for the example integration
• matched the tscircuit.com data flow:
  • workspace files
  • fsMap
  • mainComponentPath
  • render lifecycle hooks
• moved @tscircuit/runframe to devDependencies since it is only needed for local examples
• added the required runframe-side dev dependencies so the example works locally
• pinned Vite dependency optimization for @tscircuit/runframe/runner to make Cosmos resolution stable

Why

This makes the repo a better proving ground for the real tscircuit.com integration by providing a working local drop-in style example instead of an isolated editor-only fixture.

That improves confidence for future editor-preview work and makes it easier to iterate on the Monaco workspace API against the actual runframe contract used upstream.

Validation

• bun run typecheck
• bun run build
