Adds the family backlog standard to the root index (open work = Gitea issues,
shared label set, BTDB excluded) and converts components/*/GAPS, hosted-lib
CLAUDE.md notes, code-reviews, infra/glauth and plan docs to banner + issue
pointers (scadaproj #5-#19, ScadaBridge#79).
Configuration is now adopted across all three sister apps (local branches),
so flip the status lines in CLAUDE.md, components/configuration/GAPS.md, and the
lib README/CLAUDE.md from 'not adopted' to adopted (also corrects 27->42 tests).
Adds the brainstorm design doc + bite-sized implementation plan (+tasks.json)
under docs/plans/ that drove the adoption.
