Pull request overview

This pull request introduces a Go-based implementation of the Agent Development Kit (ADK) for Kagent, enabling declarative agent images with support for Azure OpenAI and Anthropic models. The implementation maintains parity with the existing Python-based ADK while providing a native Go alternative.

Changes:

• Adds comprehensive Go ADK implementation in go-adk/ directory with core utilities, skills management, and LLM model adapters
• Introduces CRD schema updates to support custom image overrides via spec.image field
• Implements build infrastructure for the Go ADK container image (app-go)
