3.15 builds (also) contain code compiled for 3.14

Looking at the pre-compiled `.pyc` files, everything in the 3.15 [unix](https://conda-metadata-app.streamlit.app/?q=conda-forge%2Flinux-64%2Fpython-3.15.0rc2-hcd007b5_101_cp315.conda) [builds](https://conda-metadata-app.streamlit.app/?q=conda-forge%2Fosx-arm64%2Fpython-3.15.0rc2-h8bd0d97_101_cp315.conda) appears to be duplicated between 3.14 & 3.15, e.g.
```
lib/python3.15/__pycache__/io.cpython-314.pyc
lib/python3.15/__pycache__/io.cpython-315.pyc
```
and so on

Start by inspecting the conda-forge/python-feedstock build configuration and comparing the pre-compiled files in the linked unix and osx-arm64 3.15 artifacts. The issue is resolved when those artifacts no longer include cpython-314.pyc files under the Python 3.15 __pycache__ directories.
