Description
The ChaosCenter Developer Guide currently lacks an overview section. Adding an introductory overview will help developers understand the purpose, architecture, and scope of the guide before diving into setup and usage instructions.

Proposed changes
• Add a new Overview at the top of the guide with the following content:

ChaosCenter is the control plane for LitmusChaos, providing a web-based interface and APIs to manage chaos experiments on Kubernetes clusters. It consists of a backend (GraphQL server, Authentication server, MongoDB) and a frontend (React) component. This guide walks you through setting up ChaosCenter locally, running the required services, and connecting your Kubernetes infrastructure to execute and monitor chaos experiments.

The document assumes a local development environment and is not recommended for production or shared clusters. By the end of this guide, you will have a fully functional ChaosCenter instance capable of managing chaos workflows and integrating with Litmusctl or ChaosCenter-managed infrastructures.
