fixed async_client initialisation

[mogith-pn]

Asynchronous Client Update

• Added an async_client property to the Model class, which initializes and returns a ModelClient instance configured with an async stub. This allows separation between synchronous and asynchronous client operations.

• Updated asynchronous methods (async_predict, async_generate, async_stream) to use self.async_client instead of self.client, ensuring proper usage of async stubs for async operations. [1] [2] [3]

• Modified the __getattr__ method to delegate calls to async methods (those starting with async_) to the async_client, while other methods continue to use the regular client. This ensures method calls are routed to the appropriate client instance.

• Added the _async_client attribute to the class initialization to store the async client instance, mirroring the existing _client attribute for synchronous operations.

Pull Request Overview

This PR fixes asynchronous client initialization in the Model class by introducing proper separation between synchronous and asynchronous client instances. The changes ensure that async operations use dedicated async clients with proper stub configurations.

Key changes:

• Added a new async_client property that creates a dedicated async client instance
• Updated all async methods to use the new async client instead of the synchronous client
• Modified attribute delegation to route async methods to the appropriate client
