date: end-july (free-threading push)

wanted:

• reducing the number of objects per release by 33%
• numpy-2.5, numba-0.66
• Python-3.15.0rc1 with binary packages
• ai local
• simplify WinPython maintenance
• pylock.toml for micropip (as the next frontier)
• pypi wppm README page is inadequate... may have to do a separate README
• Winpython on arm experiment ?

remark:

• python-3.15 with free-threading should get massively rapid adoption, because of speed-up
• windows on arm shall get a boost
• jupyterlite, because of PEP-783, shall get a massive boost
