Test Suite for Reasoning Content Consolidation Feature

This test suite validates the "Consolidate Reasoning for Non-Streaming Responses" feature
that ensures thinking (reasoning) content is properly consolidated with body content for
non-streaming responses.

Test scenarios:
1. Content consolidation with both reasoning and body content
2. Content consolidation with only reasoning content
3. Content consolidation with only body content
4. Content consolidation with empty content
5. Efficient chunking for large responses
6. Usage stats calculation with consolidated content
7. Tool calls handling with consolidated content

Run with: python tests/test_reasoning_consolidation.py
