chore(deps): Update dependency fastmcp to 3.4.2

[robander]

Description

Package bump fastmcp to pick up latest version of the starlette dependency. This is a recreation of #292 after a rebase to fix conflicts.

This PR was originally submitted to update starlette, but revised to get the latest fastmcp which now updates starlette.

Fixes GHSA-86qp-5c8j-p5mr

This dependency is used by FastAPI, but there is not a version of FastAPI that pins starlette. It looks like they will not be forcing an update, based on a comment here: https://github.com/fastapi/fastapi/discussions/15593and#discussioncomment-17065958
