Store management library based on react context and observers

/**
 * Creates a new registry to hold internal stores for the current scope.
 *
 * This function returns an `IRegistry` object containing several collections (e.g., `Map`, `Set`)
 * that are used to store mutable data such as query providers, signal listeners, context instances,
 * context states, services references, observers, and subscribers within the current scope.
 * The registry facilitates the management and access of these stores during the application's lifecycle.
 *
 * @returns {IRegistry} The newly created registry containing various internal stores used for scope management.
