[Demo] MCP using Clerk directly as the OAuth Provider

WIP

• Instead of hosting our own OAuth provider on the same worker, delegates everything to use Clerk as the OAuth provider
• Supports dynamic client registration with Clerk
• Does not work unless we make changes to mcp-remote and the MCP TypeScript SDK

Great PR...eager to see it merged.

With in-context-learning, reasoning/thinking models, tool use/function-calling (in loops) now already so good, seeing these solutions for agent auth and memory (Graphiti, CF Workers Durable Objects, etc.), start to emerge is starting to really flesh out Karpathy's LLM OS concept.
