Share a single warm connection to common chains (individuality, bulletin, assethub) for all Applications to use

In reference to Reusable Components

Products should not have to worry about fetching chain types/descriptors or opening fresh connections to chains (which makes app startup slower)

All apps will be interacting with the same 3 chains (asset hub, bulletin, individuality). The Product SDK should expose some unified typed interface to these chains, which is routed through a warm connection the Host owns making apps more snappy on startup. The Host would own which environment this points to (Paseo vs Polkadot vs Preview Net)

Something like:

import { chains } from "@novasamatech/product-sdk"

chains.assetHub.<regular papi TypedAPI>
chains.bulletin.<regular papi TypedAPI>

Start with the linked Reusable Components document and the Product SDK and Host entry points. Trace how chain types, descriptors, and connections are currently obtained for individuality, bulletin, and asset hub. Done means the SDK exposes typed interfaces for all three chains through warm Host-owned connections, with the Host selecting the environment.
