Review follow-up. electron-builder 26.15.3 pulls @electron/rebuild 4, whose
engines are `node >=22.12.0` (master was on @electron/rebuild 3, `>=12.13.0`),
and the root postinstall runs `electron-builder install-app-deps` on every
install. CI already runs Node 22, but nothing in the repo said so — no
`engines`, no `.nvmrc` — so a contributor on an older Node would have hit a
confusing rebuild failure instead of a clear one.
