Node.js Initializer 函数无法在本地环境触发，发布到线上后可以触发

### 配置的Initializer函数在本地运行时无法触发，发布到线上后可以触发

Start with template.yml and demo.js, then run the reported `fun local start` flow and compare its logs with the `fun deploy` logs. Trace the local initializer handling around `demo.initializer` and the missing `x-fc-initialization-timeout` header. Done means the local run invokes the initializer before `demo.handler` without the reported error.
