WHAT: Fix critical CLI crash with content.filter() error and implement OpenAI Responses API integration with comprehensive testing
WHY: CLI was crashing with 'TypeError: undefined is not an object (evaluating "content.filter")' when using OpenAI models, preventing users from making API calls. Additionally needed proper Responses API support with reasoning tokens.
HOW:
• Fix content extraction from OpenAI response structure in legacy path
• Add JSON/Zod schema detection in responsesAPI adapter
• Create comprehensive test suite for both integration and production scenarios
• Document the new adapter architecture and usage
CRITICAL FIXES:
• claude.ts: Extract content from response.choices[0].message.content instead of undefined response.content
• responsesAPI.ts: Detect if schema is already JSON (has 'type' property) vs Zod schema before conversion
