Contributing FastMCP Toolset

[strawgate]

Description

Right now Pydantic AI is implementing its own MCP client which means we're on the hook for #1844, etc.

I am working on implementing a FastMCP Toolset which uses the MCP Proxy support in FastMCP for mounting MCP Servers and making their tools available / callable. This means that as capabilities become available in FastMCP (Middleware, OAuth, OpenAPI, Tool Transformation) they are usable in Pydantic AI for "free".

FastMCP supports building an MCP Config using type-safe models as well as taking the standard "mcp.json" format that is common among IDEs and other frameworks.

I'll make a draft PR for this at some point as I'm building this anyway but would love to contribute it
