chore: monorepo - plugin, backend und hilfsdaten in einem repo
- Eltern-Ordner ist jetzt EIN Git-Repo (statt getrennter Repos). - root .gitignore haelt Secrets (.env), node_modules, DB und Build-Artefakte raus. - release.ps1: manueller Release (ZIP bauen + ans Backend laden). - root README mit Struktur und Release-Ablauf.
