I think we want to avoid uv pip, and instead do something like uv sync --extra re2?: https://docs.astral.sh/uv/concepts/projects/sync/#syncing-optional-dependencies

one other minor thing, if we want: could install the google-re2-stubs package as a dev dependency, which would give us type info for re2 (and we could nix the ignore here).

re2as an optional dependency to protovalidate-python. With this configured, users can choose to optionally install re2 if they explicit re2 functionality.For example
pip install protovalidate[re2]Note that while CEL requires re2 as part of the spec, our current version of cel-python (v0.2.0) doesn't. We are unable to upgrade cel-python beyond v0.2.0 at this point due to some outstanding issues, so since re2 now supports Python 3.13, we're adding it as an optional dep directly to protovalidate-python rather than the re2 workaround we had previously implemented.
