Move subscription shape typing from useTaiiNet to useSubscription

[Copilot]

useTaiiNet previously carried a global subscription type map, which constrained consumers to one shape map per hook instance. This change moves shape typing to useSubscription, so each subscription call can declare its own typed shape map.

• API typing shift

  • Removed the generic type parameter from useTaiiNet / UseTaiiNetResult.
  • Updated UseSubscriptionHook so typed mapping is declared per invocation (useSubscription<...>()), while preserving the untyped fallback overload.

• Consumer-facing usage update

  • Updated React usage to type subscriptions at call sites instead of hook creation time.
  • This supports multiple differently shaped subscriptions from the same useTaiiNet() result.

• Docs and contract alignment

  • Updated README examples to reflect the new API surface.
  • Updated hook test typing to match the new call pattern.

type FeedSubscriptions = {
  tweet: { type: "tweet"; body: string };
};

const { useSubscription } = useTaiiNet();
const { data, sendData } = useSubscription<FeedSubscriptions>({ type: "tweet" }, { backlog: true });
