sha2 module still referenced even if not built (3.12.11)

デフォルトで .sha2 モジュールが無効になっている build.zig から始め、次に traceback に表示されている Python 3.12 の hashlib.py と random.py の参照を調べます。再ビルドし、REPL の modules check を使用して、無効化された sha2 サポートによって例外や利用できない _sha2 コードへの参照が発生しなくなったことを確認します。

The module .sha2 is explicitly disabled in build.zig by default. The build completes fine, but when checking for modules in the REPL, throws exceptions:

help> modules

Please wait a moment while I gather a list of all available modules...
