Reorganize client generated in Telescope

[NorOldBurden]

In the future, I’d like to deprecate the current clients being all separated and move towards this being the default way to build clients.
So perhaps we can figure something out now that allows us to work towards this.

for example, we could toggle it at the top level of the rpcClients
rpcClients: {
// Feature flag to control client generation style
clientStyle: "combined" | "scoped" | "unified"
