chore(deps): weekly dependency update

[github-actions]

Automated weekly dependency update via python scripts/update-matrix-latest.py && uv lock --upgrade.

⚠️ Provider SDK packages changed. A human needs to re-record cassettes locally before merging.

Summary by Sourcery

Refresh the Python dependency matrix and lockfile to the latest supported package versions.

Enhancements:

• Update the dependency matrix to newer releases across provider SDKs, agent frameworks, evaluation tools, and supporting libraries.

Build:

• Regenerate the Python dependency lockfile with the upgraded package set.

Tests:

• Re-record provider integration cassettes locally to reflect SDK updates before merging.

Reviewer's Guide

Automated weekly dependency refresh updates the matrix’s latest package versions and regenerates the lockfile. Because multiple provider SDKs changed, reviewers should verify compatibility and require local cassette re-recording before merge.

File-Level Changes

Change	Details	Files
Refresh the dependency matrix’s latest provider and tooling versions while preserving pinned historical compatibility entries.	Update latest versions for provider SDKs and integrations, including OpenAI, Anthropic, Cohere, Agents SDK, LiteLLM, Google, Mistral, and framework packages. Regenerate the uv lockfile to resolve the upgraded dependency graph. Retain existing historical matrix versions for compatibility testing.	py/pyproject.toml py/uv.lock

**Updated SDK integration tests fail**

When the updated `latest` matrix sessions run before their cassettes are re-recorded and committed, nox passes `latest` to the cassette fixture, which replays the existing `cassettes/latest/` recordings. CI's VCR `record_mode="none"` cannot record changed requests, so replay matching or response handling fails and the integration sessions fail.

Re-record and commit matching `latest` cassettes for the updated SDK versions.
