add: PoolAgentDriver entrypoint (#479)

Update project configuration to register a new driver entry point. This change ensures that the PoolAgentDriver is correctly exposed and accessible within the SDK's universal agent framework.

### Highlights

* **Entrypoint Registration**: Added the PoolAgentDriver to the gcl_sdk_universal_agent entry points in pyproject.toml to facilitate its discovery.
