This was a matter of running "mtxrun --generate". After that, mtx-context.lua is found:

% mtxrun --locate  mtx-context.lua
/usr/local/texlive/2026/texmf-dist/scripts/context/lua/mtx-context.lua

But even then, processing the example file with mkiv doesn't work:

% context --luatex --autogenerate example.tex
mtx-context     | redirect luametatex -> luatex: luatex --luaonly --socket "/Library/TeX/texbin/mtxrun.lua" --script mtx-context --luatex --autogenerate example.tex --redirected
mtxrun          | unknown script 'mtx-context.lua' or 'mtx-mtx-context.lua'

Using lmtx, things don't work either, but for a different reason:

% context --autogenerate example.tex 
mtx-context     | warning: no format found, forcing remake (commandline driven)

I imagine some ConTeXt initialization needed to be performed after installing TL 2026, and wasn't. This said, I'm no ConTeXt user, so maybe I'm completely off-track and I'm not doing things the way they should be.
