8617: JMC MCP server

[thegreystone]

This PR adds an MCP server so that recordings can be easily analyzed from within AI harnesses, such as Claude code, codex and/or any other harness supporting MCP servers.

The MCP server can be built as a native binary using Graal VM native image. Use the documentation for your particular harness to understand how to install it.

Note that the choice of model matters enormously when using the MCP server. I have had very good results with Fable.

@robilad, would this be more palatable? It's basically just giving agents access to JMC core through an MCP server.
