v0.2.1 – Auto-exit server after tool call

Changes

• Auto-exit after tool call: The MCP server now exits after each tool call completes, instead of staying alive consuming resources. Uses CancellationToken + serve_with_ct for clean shutdown.
• The server is restarted fresh by the CLI on each subsequent call — refresh is fast enough that this is cheaper than keeping a long-running process.
