[Runtime] The command hook should return the component instance proxy

core-vapor/packages/runtime-core/src/directives.ts

Lines 92 to 94 in 597eae4

	const instance =
	(getExposeProxy(internalInstance) as ComponentPublicInstance) ||
	internalInstance.proxy

Should be consistent with the existing runtime, returning a proxy object for the component instance

Is it essential to have a PublicInstance in Vapor mode? Since in vapor mode we don't need to support Options API.

Most properties of public instances benefit from the Options API. I think that when only Composition API is supported, these properties can be obtained using macros defineXXX or getCurrentInstance.

Also, we can plan to publicize some properties returned by getCurrentInstance.

P.S. Sorry for my late reply. My focus isn't on Vapor in recent days.

At this stage, we can avoid public instances and consider not distinguishing between internal and public in the future.
