feature patch

pydantic-ai v2.37.0 introduces support for the glm-5.3-flash model and includes several bug fixes. This integration enhances AI model handling, while the fixes address issues across span queries, finish reasons, tool calls, API routing, and agent tracebacks. Developers using pydantic-ai for AI model interactions, particularly those working with Z.AI or Google Vertex/Gemini APIs, will benefit. The update improves stability and broadens compatibility with different AI service providers and their specific behaviors.
