feat(ops): Add MCP ops

[msonnb]

Description

Adds ops and description/name rules for mcp.server, mcp.notification.client_to_server, and mcp.notification.server_to_client, as already used by the JS SDK.

PR Checklist

• I have run yarn test and verified that the tests pass.
• I have run yarn generate to generate and format code and docs.

If an attribute was added:

• The attribute is in a namespace (e.g. nextjs.function_id, not function_id)
• I have used the correct value for apply_scrubbing (i.e. manual or auto. Use never only for values that should never be scrubbed such as IDs)

If an attribute was deprecated:

• I've followed the policies described in CONTRIBUTING.md

We only have mcp.server in Python.
The other ops look strange but that's okay I guess.
