test: add comprehensive tests for ClaudeCodeProvider
Addresses code review feedback about missing automated tests for the ClaudeCodeProvider. ## Changes - Added unit tests for ClaudeCodeProvider class covering constructor, validateAuth, and getClient methods - Added unit tests for ClaudeCodeLanguageModel testing lazy loading behavior and error handling - Added integration tests verifying optional dependency behavior when @anthropic-ai/claude-code is not installed ## Test Coverage 1. **Unit Tests**: - ClaudeCodeProvider: Basic functionality, no API key requirement, client creation - ClaudeCodeLanguageModel: Model initialization, lazy loading, error messages, warning generation 2. **Integration Tests**: - Optional dependency behavior when package is not installed - Clear error messages for users about missing package - Provider instantiation works but usage fails gracefully All tests pass and provide comprehensive coverage for the claude-code provider implementation.
