/**
 * Creates a recursive async proxy for a singleton class that delays method and property access until the instance is initialized.
 * Supports nested property chains like `await proxy.core.agencies.findById(id)` by recursively wrapping each property access
 * in a new proxy, resolving the full path only when the chain is invoked (called as a function or awaited).
 *
 * @param cls - A class with a static `getInstance` method that returns a promise resolving to the class instance.
 * @returns A proxy object that intercepts property access and method calls, ensuring the instance is initialized before resolving.
