PR Review: Update pydantic-ai to >=1.46.0

Summary

This PR updates the pydantic-ai dependency from >=1.44.0 to >=1.46.0. This is a minor version bump managed by Renovate.

Code Quality ✅

• Clean dependency update with minimal changes
• Only affects the examples dependency group, not core dependencies
• Lock file properly updated with transitive dependencies

Key Changes

1. New dependency: xai-sdk (1.5.0) added as a transitive dependency
2. New dependency: grpcio (1.76.0) added as a transitive dependency
3. Updated packages: pydantic-ai, pydantic-ai-slim, pydantic-evals, pydantic-graph all bumped to 1.46.0

Observations

Positive:

• According to the release notes, v1.46.0 adds XaiModel and bumps MCP dependency versions
• The update is confined to the examples dependency group (pyproject.toml:42)
• No breaking changes expected based on semantic versioning

Considerations:

1. New transitive dependencies: grpcio (~6-8MB) and xai-sdk add ~70+ new wheels to lock file. This increases installation size for the examples group.
2. Compatibility check needed: The example code in examples/anthropic_comparison/mcp_optimizer_agent.py:11-15 uses pydantic_ai imports. Should verify these still work with 1.46.0.
3. Untested change: The diff shows no test updates. Consider running the examples to ensure compatibility.

Recommendations

1. ✅ Approve: This is a standard dependency update with no breaking changes
2. ⚠️ Test before merge: Run examples/anthropic_comparison/mcp_optimizer_agent.py to verify the agent still works with the new version
3. 📝 Optional: Consider pinning major version if stability is critical (e.g., >=1.46.0,<2.0.0)

Security & Performance

• ✅ No security concerns identified
• ℹ️ Minor performance impact from larger dependency footprint (grpcio)
• ✅ No breaking changes to public APIs used in codebase

Verdict: Safe to merge after verification testing of example code.
