Add progress and logs to a slow tool

Your research server has an add_all tool that sums a list of numbers, working through them one at a time. Right now it stays silent, so the client can't tell how far along it is. You'll log a message when it starts, then report progress after each number so the client can render a smooth, advancing progress bar.

FastMCP and Context are imported and the server mcp is created. run_tool(numbers) runs your tool through a real MCP client–server session and collects what the connected client receives into the lists LOGS and PROGRESS.

Use ctx.info() to log the message "Adding the numbers..." when the tool starts.
After adding each number, call ctx.report_progress() inside the loop.
Report the count done so far (i + 1) out of the total (len(numbers)).
