Method runNonInteractive

packages/core/src/core/subagent.ts:344–469

* Runs the subagent in a non-interactive mode. * This method orchestrates the subagent's execution loop, including prompt templating, * tool execution, and termination conditions. * @param {ContextState} context - The current context state containing variables for prompt templating. * @r

(context: ContextState)

   * @returns {Promise<void>} A promise that resolves when the subagent has completed its execution.
