feat(behavior-tree): add pure BehaviorTreePlugin class for Cocos/Laya integration

• Added BehaviorTreePlugin class that only depends on @esengine/ecs-framework
• Implements IPlugin interface with install(), uninstall(), and setupScene() methods
• Removed esengine/ subdirectory that incorrectly depended on @esengine/engine-core
• Updated package documentation with correct usage examples

Usage:

import { Core, Scene } from '@esengine/ecs-framework';
import { BehaviorTreePlugin, BehaviorTreeBuilder, BehaviorTreeStarter } from '@esengine/behavior-tree';

Core.create();
const plugin = new BehaviorTreePlugin();
await Core.installPlugin(plugin);

const scene = new Scene();
plugin.setupScene(scene);
Core.setScene(scene);
