Dependabot Review

Recommendation: SAFE TO MERGE

This bumps sphinxcontrib-mermaid requirement from >=0.9.2 to >=2.0.1 in python/pyproject.toml. All CI checks pass. This is a dev/docs dependency for rendering Mermaid diagrams in Sphinx documentation -- no impact on production code.

Safe to merge -- docs dependency, all CI passes.
