fix: chat stuck issue

[tcm390]

I encountered an issue where, if the chat failed (e.g., the useModel function exceeded the rate limit), an error would be shown but the chat would get stuck displaying "agent is thinking." In this state, the user could no longer type unless they refreshed the page.

This PR fixes the issue by calling the notifyMessageComplete function inside the onComplete handler of emitEvent

Bug: Chat Stuck Due to Error Handling Gaps

The onComplete callback, intended to ensure notifyMessageComplete is always called to unstick the chat, has two error handling deficiencies:

1. It lacks a try-catch for getRoom() and getWorld() calls, meaning notifyMessageComplete won't be called if they throw.
2. The onComplete callback itself is not invoked if the emitEvent call fails.
   Both scenarios can leave the chat in a "thinking" state.

Lines 474 to 487 in b289348

	await this.runtime.emitEvent(EventType.MESSAGE_RECEIVED, {
	runtime: this.runtime,
	message: agentMemory,
	callback: callbackForCentralBus,
	onComplete: async () => {
	const room = await this.runtime.getRoom(agentRoomId);
	const world = await this.runtime.getWorld(agentWorldId);
	const channelId = room?.channelId as UUID;
	const serverId = world?.serverId as UUID;
	await this.notifyMessageComplete(channelId, serverId);
	}
	});
