Add Claude Code Integration for Autonomous Coding on Amazon Bedrock AgentCore

# Add Claude Code Integration for Autonomous Coding on Amazon Bedrock AgentCore

## Overview
This issue proposes adding Claude Code as a new integration for Amazon Bedrock AgentCore, enabling autonomous code generation and deployment capabilities without requiring an Anthropic API key.

## What is Claude Code?
Claude Code is an AI-powered coding assistant that can autonomously:
- Generate complete applications from natural language descriptions
- Deploy infrastructure and applications to AWS
- Refactor and improve existing codebases
- Create comprehensive test suites
- Generate documentation
- Perform code migrations between frameworks

## Integration Benefits
- **No Anthropic API Key Required**: Leverages Amazon Bedrock for inference
- **Autonomous Operation**: Runs without human intervention in headless mode
- **Cost Effective**: ~$0.30-0.50 per complex coding task
- **Production Ready**: Docker containerized with full AgentCore integration
- **AWS Native**: Can deploy to S3, CloudFront, Lambda, and other AWS services

## Technical Implementation
The integration includes:
- Docker container with Node.js and Claude Code CLI pre-installed
- Python agent wrapper for AgentCore compatibility
- Manual deployment script for custom Docker image requirements
- IAM role configuration for AWS service interactions
- Example prompts demonstrating various use cases

## Use Cases
1. **Rapid Prototyping**: Generate full-stack applications from descriptions
2. **Infrastructure as Code**: Create CloudFormation/CDK templates
3. **Code Modernization**: Migrate legacy applications to modern frameworks
4. **Automated Testing**: Generate comprehensive test coverage
5. **Documentation Generation**: Create technical documentation from code
