// a SIGKILL'd client, they don't fire and the server lingers as an orphan. If no
// client traffic arrives within the idle window, exit. Every JSON-RPC request
// reaches us as stdin data (the SDK's stdio transport also listens on 'data', so
// our listener is additive), so an actively-used server keeps resetting the timer
// and never times out. Configure with OMNIFOCUS_MCP_IDLE_TIMEOUT_MINUTES
// (default 30; set 0 to disable). See src/utils/idleTimeout.ts.
