arcade deploy for MCP Servers

[EricGustin]

Blocked by #614 (and the reason for failing tests)

PR Description

arcade deploy will deploy your local MCP server to Arcade. arcade deploy should be executed at the root of your MCP Server package. Before deploying, the command runs your server locally to ensure your project is setup correctly and the server runs properly. arcade deploy assumes your entrypoint file will execute MCPApp.run when the file is invoked directly. This means you must either have an if __name__ == "__main__" block that contains MCPApp.run, or MCPApp.run` should be top-level code (unindented living directly in the body of the file).

I'm reviewing with an eye to DX, and I think there are some minor things we can do to make this a really tight experience.
