MCP 2 removes FastMCP and runs synchronous tool handlers concurrently in worker threads. The servers rely on serialized state and cache access. Update to MCPServer and use one shared lock context around each server's tool bodies to preserve MCP 1 ordering. Test concurrent requests for one uncached package and verify that it is cloned only once.

MCP 2 removes FastMCP and dispatches synchronous tool handlers through
worker threads. The servers relied on serialized execution for mutable
state and the dist-git cache lifecycle.
Update the dependency to 2.0.0, use MCPServer, and serialize tool calls
with a shared lock per server to preserve MCP 1 ordering. Add a regression
test that sends concurrent MCP requests for the same uncached package and
verifies it is cloned only once.
