fix(core): host-dev context 补 getEngine()=null 桩——P2 契约自洽(契约加 getEngine 须参考实现跟上)

createHostDevContext 镜像 getAudioContext 范式补 engineFactory 选项+getEngineShared(无工厂返null+告警一次+lazy单例+工厂抛错降级)+ctx.getEngine();155测全绿(契约加方法+桩跟上不破现有测试,#6风险实证清除)。集成段注入真实engineFactory背书littlejsengine=引擎import唯一落点
自核(对抗复审agent解析失败死,关键检查主会话亲验):zzfxG返样本数组(synthSfx正确避开会播放的zzfx,播放归缺件补层)+schema packageUrl/immutable declared非required(存量manifest仍合法)
