Update VS Code Walkthrough to Include New Features: GitHub Copilot x Extension Chat Hooks, Kaito Integration, and Auto-Deployment

We recently release 2 major features, and previously an auto-deployment feature as well.

**Description:**

We have recently added three significant features to our VS Code extension, and the current walkthrough does not reflect these updates. To provide a better onboarding experience for users, we need to re-adjust the walkthrough content and include detailed steps for:

### **New Features to Update in Walkthrough:**

1. **GitHub Copilot x VS Code Extension Chat Hooks**
- **Context:**
- This feature introduces enhanced collaboration by integrating GitHub Copilot directly into the extension's chat interface, allowing users to receive AI-powered code suggestions and guidance seamlessly.
- **Usage:**
- Show how users can enable the GitHub Copilot integration within the chat interface.
- Provide examples of how to utilize chat hooks for improved coding assistance.

2. **Kaito Integration**
- **Context:**
- The Kaito integration introduces advanced capabilities, enabling more intelligent code search, contextual suggestions, and enhanced navigation within the project.
- **Usage:**
- Guide users on how to set up and enable Kaito within the extension.
- Demonstrate use cases, such as advanced search features and code insights.

3. **Auto-Deployment Feature (Previously Released)**
- **Context:**
- Although this feature was previously released, it has not been adequately covered in the current walkthrough. It provides automated deployment capabilities directly from the extension, simplifying the CI/CD process for users.
- **Usage:**
- Provide step-by-step instructions on how to configure auto-deployment.
- Include best practices for setting up deployment triggers and managing environments.

### **Action Items:**

- [ ] Update the walkthrough content to include the GitHub Copilot x Extension Chat Hooks integration.
- [ ] Add a new section for Kaito Integration with detailed usage instructions.
- [ ] Revise and expand the auto-deployment feature section to ensure clarity and user understanding.
- [ ] Update screenshots and examples in the walkthrough to reflect the latest UI and feature changes.

### **Additional Notes:**

- Ensure the walkthrough sections are easy to navigate, with clear headings and usage examples for each feature.
- This update aims to provide users with a comprehensive guide to leveraging these new features effectively, enhancing the overall user experience.

Start by locating the current VS Code walkthrough and its screenshots and examples, then compare it with the documented GitHub Copilot chat hooks, Kaito integration, and auto-deployment flows. Verify that each section covers setup, usage, navigation, and current UI screenshots.
