luaotfload-tool --diagnose=permissions fails because it looks for luaotfload-names.luc in uncompressed format

[cfr42]

Ref.: https://tex.stackexchange.com/q/715533/ (but the question describes multiple luaotfload-tool bugs)

luaotfload | diagnose : =============== file permissions ==============

attr    /home/username/.texlive2024/texmf-var/luatex-cache/generic/names/luaotfload-names.luc   nil

This fails because the file doesn't exist. luaotfload-names.luc is present, but only in compressed format as luaotfload-names.luc.gz. This is apparently fine when using LuaTeX but not fine with luaotfload-tool.

Comparison/Related

I'm reporting separately from #281 as the cause seems different and, unlike that bug, this one doesn't appear to have existed in 2020. #168 says that 'all other self-tests' --- presumably including the permissions check --- were fine.

It looks to me that I am hitting this as well. Is there a plan to do a release that can be downloaded with TeX Live update?
