feat: port Rust core runtime

 Rename the exported `Provider` transport type to `WireProvider` to make its role explicit. It is the low-level SCALE-wire-frame pipe (a `MessagePort` or iframe `postMessage` channel) that `createTransport` runs on. The `createIframeProvider` / `createMessagePortProvider` factories are unchanged; only the type name moves. Consumers importing `Provider` should import `WireProvider` instead.

 Add the `@parity/truapi/sandbox` entry point: host-environment detection (`isCorrectEnvironment`), a lazily-built cached client (`getClientSync`, `null` outside a host container), and a `subscribeConnectionStatus` connected/disconnected listener. Browser-embedded hosts can bootstrap a client without assembling the transport by hand.
