pydantic support

did anyone try pydantic with componentize-py?

I ran into this issue and was told to raise an issue here.

I am not able to compile the code to a wasm binary
error:

I installed the modules in my venv

Not sure what is going on? (edited)

まず、参照されている `rec.py` と `apis/topo/v1alpha1/topology_types.py` の import を使って、issue の `just build-guest-python` コマンドを再現します。`componentize-py` が `pydantic_core._pydantic_core` をどのようにパッケージ化またはロードするかを追跡します。pydantic ベースの guest が正常にコンパイルできるか、またはサポートされる制限が明確に確立されれば完了です。
