Method presentAssistantMessageSafe

src/core/task/Task.ts:366–380

* Fire-and-forget wrapper around `presentAssistantMessage` that swallows the * expected cancellation rejection (the presenter throws when `this.abort` is set) * and logs any other failure. Keeping it non-blocking preserves the streaming * presenter's self-locking semantics while preventing unh

()

	 * from crashing the extension host.
