Initial commit: reorganized source tree

- backend/: 13 Maven modules (cw-elevator-application, cloudwalk-cloud, intelligent-cwoscomponent, ninca-crk, etc.)
- frontend/: 4 Vue projects (elevator-front, cwos-portal, alarm-front, front_acs) + decompiled + scripts
- scripts/: build, test-env, tools (Docker Compose, service templates, API parity)
- docs/: AGENTS.md, superpowers specs, architecture docs
- .gitignore: standard Java/Maven exclusions

Moved from legacy maven-*/ root layout to backend/ organized structure.
