Need a implemention for `context-proxy` pattern

[lichaozhy]

• A top identifier in @produck/charon?
• An independent module like @produck/charon-ref?

Which one above or else?

[LiuQ-Q]

I think we can add a top identifier in @produck/charon-browser, because it runs on browser and user can manage versions easier.

I prefer this feature to be implemented in @produck/charon-browser.

1. Backend projects are not used
2. if use independent module @produck/charon-ref, it will increase project maintenance costs
3. Implementation in @produck/charon-browser reduce user use cost

It MAY be a independent module. The context-proxy pattern is NOT for most of developer. It should keep charon pure then optimizing context-proxy implementation.
