Implemented complete Claude Code support alongside existing Aider integration:
- ClaudeCodeSolver strategy with programmatic Claude Code CLI usage
- Intelligent model detection to route Anthropic models to Claude Code
- Shared post-solver cleanup function to eliminate code duplication
- CLAUDE_CODE_MESSAGE_FORMAT constant for maintainable prompts
- Comprehensive test suite with 18 passing tests
- Automatic ANTHROPIC_API_KEY environment setup
Users can now specify any Anthropic model (claude, sonnet, haiku, opus) to use Claude Code, while other models continue using Aider.
