[NTG-context] \pi not defined in latest MkIV

Hi Hans, \pi doesn't seem to be defined in MkIV anymore. I'm using the latest from the standalone distribution, although the issue is also present in the TL25 pretest. Minimal example: % engine=luatex \startTEXpage \m{\pi} \stopTEXpage This was originally reported on the TeX Live list: https://tug.org/pipermail/tex-live/2025-February/051173.html Thanks, -- Max
