Reorganize project structure: move docs and scripts to proper directories

Changes:
- Created scripts/ directory for build and utility scripts
- Moved build-for-airgap.sh to scripts/
- Moved check-ready.sh to scripts/
- Kept quickstart scripts in root for easy access
- Moved HELM-DEPLOYMENT.md to docs/

Updated references:
- README.md: Updated link to docs/HELM-DEPLOYMENT.md
- docs/DEPLOYMENT.md: Updated paths to scripts/build-for-airgap.sh
- quickstart-airgap.sh: Updated path to scripts/build-for-airgap.sh
- scripts/check-ready.sh: Updated self-reference path
- helm/warehouse13/QUICKSTART.md: Updated HELM-DEPLOYMENT.md path
- helm/README.md: Updated HELM-DEPLOYMENT.md path

Directory structure now:
