Lucas Gomide ca220cdc23 fix: use persistent event loop for MCP operations to prevent cancel scope errors ...

Replace per-call asyncio.run() with a single persistent background event
loop for all MCP operations. The MCP SDK's streamable HTTP transport uses
anyio task groups whose cancel scopes must be entered and exited on the
same event loop and task. Creating a throwaway loop per tool call caused
"Attempted to exit cancel scope in a different task" RuntimeErrors during
cleanup, preventing MCP tools from working reliably
