Swiss AI Hub v0.316.0

Added

• 🦾 New IMAP Agent: Introduced a powerful new ImapAgent designed for non-conversational mail automation. This
  agent can independently read and move emails, and automatically draft LLM-generated replies for incoming messages.
• 📄 Docker Service Integration: The new ImapAgent is fully integrated as a deployable Docker service, including
  comprehensive environment variable configurations for seamless deployment and operation across various deployment
  stages (build, latest, local, nightly, and GPU versions).
• ⚙️ OpenTelemetry Support for IMAP Agent: The ImapAgent now supports OpenTelemetry for enhanced observability and
  tracing of its mail processing workflows.

Changed

• 🔄 Promoted IMAP Functionality: The IMAP mail automation capabilities have been promoted from a playground example
  to a core, production-ready ImapAgent within the main agent package, making it a formally recognized and deployable
  component.
• 📚 Updated Environment Variable Documentation: The deployment guide documentation has been updated to include all
  relevant environment variables for configuring the new ImapAgent and its associated services (LiteLLM, S3, MongoDB,
  NATS, Redis).
