Subject: [PATCH] fix: auto-patch Angular CLI node version constraint and
 support nvm in start scripts

- Auto-patch Angular CLI 22.1.6 node-version.js requirement from ^22.22.3 to 22.22.0 across Linux, macOS, and Windows startup scripts
- Automatically detect and load nvm in start.sh and install_deps.sh when available
- Ensure Showcase UI can be built on Cloudtop and Debian systems running Node 22.22.x without requiring root privileges
