Add Claude Explain feature for AI-powered code explanations
This PR introduces Claude Explain, a new feature that provides AI-powered explanations of compiler output directly within Compiler Explorer.
Key features:
Claude Explain functionality:
- New explain view pane
- Explains compiler output with full context of source code and compilation output
- Configurable audience level and explanation type
- Response caching to improve performance and reduce API calls
- Usage statistics display showing requests used and token counts
User experience:
- Consent flow on first use explaining data handling and privacy
- AI disclaimer banner warning about potential LLM inaccuracies
- Respects "no-ai" directive in source code for users who don't want AI processing
Privacy and security:
- Data sent to Anthropic's Claude API as documented in privacy policy
- No data used for model training
- Clear consent required before first use
- Support for opting out via "no-ai" directive
The feature is marked as beta and can be enabled via configuration.
