The submodule was described as a "stale reference copy"; it actually
tracks the active azcomputerguru/gururmm repo (the pinned commit lagging
main is normal, not stale). Also disambiguates the abandoned hyphenated
`guru-rmm` Gitea duplicate from the submodule, and notes that fresh
clones need `git submodule update --init` (now automatic in /sync).
