Implements the `openai_text_verbosity` setting for OpenAI Responses API models, allowing users to control response verbosity with 'low', 'medium', or 'high' values. The verbosity parameter is added to the text configuration when making requests to the OpenAI Responses API, providing better control over response length.

- Move verbosity code below the 'trick' to fix tests - Change verbosity logic to use elif to prevent JSON format conflicts - Add VCR cassette test with @pytest.mark.vcr() decorator - Update test to use assert result.output == snapshot() 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
🎯 **Key Achievements:**
- ✅ Fixed verbosity implementation to match OpenAI documentation format
- ✅ Successfully tested GPT-5 with 'low' verbosity setting
- ✅ Updated OpenAI package to 1.99.9 for latest features
- ✅ Implemented all of DouweM's requested changes
🔧 **Technical Changes:**
- Fixed verbosity text format: `{'format': {'type': 'text'}, 'verbosity': verbosity}`
- Moved verbosity logic below JSON 'trick' (DouweM feedback)
- Changed to `elif` to prevent JSON format conflicts (DouweM feedback)
- Added VCR test with `@pytest.mark.vcr()` decorator (DouweM feedback)
- Updated test to use `assert result.output == snapshot()` (DouweM feedback)
🧪 **Test Results:**
- GPT-5 + low verbosity: ✅ WORKING
- Test passes with proper quantum computing explanation
- VCR cassette captures successful API interaction
The implementation now correctly follows OpenAI's documentation pattern for verbosity with GPT-5.

- Resolved uv.lock conflict by regenerating lock file - Updated with latest changes from main branch - Preserved our working GPT-5 verbosity implementation 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
✅ **VCR Test Successfully Created:**
- Added test_openai_responses_verbosity() with @pytest.mark.vcr()
- Tests GPT-5 with 'low' verbosity setting
- Uses snapshot() for deterministic testing
- VCR cassette shows correct request format
🔧 **Test Details:**
- **Request:** 'What is 2+2?' with verbosity='low'
- **Response:** '4' (demonstrates low verbosity working)
- **Format:** {'format': {'type': 'text'}, 'verbosity': 'low'}
📦 **Dependencies:**
- Updated uv.lock with OpenAI 1.99.9 and other resolved dependencies
Addresses DouweM's feedback about missing VCR cassette.

Allow verbosity parameter to be combined with JSON object and JSON schema formats as per OpenAI documentation. Changed conditional from elif to if and added logic to append verbosity to existing text configuration. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>

@DouweM cool to upgrade openai to 1.99.9? |

@DouweM why are these unrelated tests failing in CI? |
