Pydantic AI 2.36.0 Release Introduces Durable Operations and Tool-Call Streaming

breaking feature patch

Pydantic AI version 2.36.0 ships with new capabilities for building robust AI agents and applications. Key enhancements include a `@durable_operation` decorator and a public backend API for integrating third-party durable execution engines, enabling long-running operations. The `clai` component now supports `--mcp-config` and tool-call streaming, improving real-time interaction capabilities. Additionally, instruction parts now have stable IDs, and `RealtimeSession.send_audio()` accepts async iterables. This release also resolves bugs related to `TestModel` generation and `ToolDefinition` caching.
