feat(responses-api-adapter): Enhanced Tool Call Conversion

Browse Source 
WHAT: Enhanced tool call handling in Responses API adapter with better validation, error handling, and test coverage

WHY: The adapter lacked robust tool call parsing and validation, leading to potential issues with malformed tool calls and incomplete test coverage. We needed to improve error handling and add comprehensive tests for real tool call scenarios.

HOW: Enhanced tool call result parsing with defensive null checking; improved assistant tool call parsing with proper validation; enhanced response tool call parsing with better structure and support for multiple tool call types; added validation for streaming tool call handling; updated tests to validate real tool call parsing from API; added multi-turn conversation test with tool result injection

Testing: All 3 integration tests pass with real API calls. Validated tool call parsing and tool result conversion working correctly. Real tool call detected and parsed successfully.
