New Features 🚀​

Agent Clients: Secure authentication​

Agents now support a more secure authentication scheme with Agent Clients. Authenticate using a generated, encrypted JWT token by creating your own client ID, secret, and public key.

This approach enables agents to run more safely, without exposing sensitive API keys in the frontend. For full implementation details refer to Agent Clients documentation
