python standalone builds from local to mirror astral ones.
It helps Winpython project to move on cloud build for free version

Procedure:

• download from python.org
• unpack via c:\WinP\bd314\python-3.14.0rc2-amd64.exe TargetDir=C:\WinP\bd314\winpython-3.14.0rc2-amd64\python InstallAllUsers=0 Include_launcher=0 InstallLauncherAllUsers=0 Include_test=0 AssociateFiles=0 Shortcuts=0 Include_doc=0
• otherwise unzip previsouly compacted python-3.14.0rc2.amd64.zip
• rename extracted sub-directory as python, if not yet python
• recompaction like astral:
  • free-threading:
    • "t" object of base level "python/*" are hard-copied over normal object (current WinPython practice)
    • tar -czvf "cpython-3.14.0rc2+20250825-x86_64-pc-windows-msvc-freethreaded-install_only_stripped.tar.gz" python
  • standard:
    • tar -czvf "cpython-3.14.0rc2+20250825-x86_64-pc-windows-msvC-install_only_stripped.tar.gz" python
