chore(deps): resolve dependabot security alerts (#502)

Bump vulnerable transitive dependency resolutions for aiohttp,
starlette, and pydantic-ai in the SDK and deprecated ADK integration
locks.

Remove CrewAI from the shared lint environment to avoid its vulnerable
chromadb transitive dependency, while keeping CrewAI integration
coverage on its dedicated nox session.
