research and design for the filecoin app proxy contract

Currently all apps using FWSS share all the state, including balance, storage usage, dataset and so on; while this feature allows datasets to be interactable, however, it can also create a weird ux as the following
- user buys and stores data in app X
- user wants to try another app Y, they go there and connect their wallet, all the data and balance from app X will show up in this app they havent even set up with

Thus, we would like to consider a Filecoin app proaxy contract, in which each app may have more ownership of their own user's dataset and services
