Add comprehensive CMW example files for issue #24

[Sukuna0007Abhi]

Summary

This PR addresses issue #24 by providing comprehensive example CMW (Conceptual Message Wrapper) files for testing and development purposes with RATSD.

Changes Made

Example Files Created

• basic-mock-tsm.json - Simple mock TSM attester example with minimal required fields
• mock-tsm-with-privilege.json - Mock TSM attester with privilege level configuration
• tsm-report-basic.json - Basic TSM report attester example
• multi-attester.json - Demonstrates multiple attesters in a single CMW collection
• tsm-cbor-format.json - TSM report using CBOR content type format
• privilege-level-3.json - Example showing maximum privilege level configuration

Documentation and Testing

• README.md - Comprehensive documentation explaining CMW structure, usage examples, and API integration
• test-examples.sh - Automated validation script for JSON syntax, CMW structure, and base64 encoding
• IMPLEMENTATION_SUMMARY.md - Technical summary of implementation approach and design decisions

Technical Implementation

CMW Structure Compliance

All examples follow the standard CMW collection format with proper __cmwc_t tagging and content type specifications for each attester type.

Validation Features

• JSON syntax validation
• CMW structure verification according to project standards
• Base64 encoding validation for auxblob and outblob fields
• Automated testing infrastructure for continuous validation

Coverage

• Mock TSM attester with JSON format and configurable privilege levels
• TSM Report attester supporting both JSON and CBOR content types
• Multi-attester scenarios demonstrating complex evidence collection
• Complete privilege level range from 0 to 3

Testing

All examples have been validated using the included test script. The validation covers:

• JSON syntax correctness
• CMW structure compliance
• Base64 encoding validity
• Content type consistency

Integration

These examples are designed to work with the existing RATSD API endpoints and support both list-options: all and list-options: selected configurations.
