Pull request overview

Updates Python package documentation snippets (AGENTS.md) to satisfy repo markdown code-block linting/pre-commit checks by aligning examples with current APIs; also updates the Python uv.lock dependency lockfile.

Changes:

• Updated durabletask AGENTS.md usage example to use TaskHubGrpcClient + DurableAIAgentClient.get_agent(...).run(...) (instead of calling a nonexistent client.run).
• Updated declarative AGENTS.md usage example to use instance factory methods (create_*_from_yaml_path) instead of nonexistent create_from_file APIs.
• Refreshed python/uv.lock, upgrading several dependency versions.
