Silent Background Task Execution Protocol (Async Daemon Management)

Overview

When an agent starts a long-running process (e.g., npm install, a Next.js dev server npm run dev, a Docker container build, or a full database migration), executing the command synchronously blocks the client for minutes.

Synchronous execution of long tasks causes severe failures:

1. Chat UI Freezes: The user interface becomes unresponsive while streaming intermediate stdout progress bars.
2. HTTP Gateway Timeouts (504s): Long synchronous commands exceed reverse proxy socket limits (60s to 120s), aborting the task midway.
3. Turn Inefficiency: The agent cannot perform other parallel investigations while blocked on a synchronous command.

The Silent Background Task Protocol configures asynchronous daemon execution using WaitMsBeforeAsync and IsDaemon parameters - allowing commands to run silently in the background while logging to disk.
