desktop/Scripts/provision-linux.sh: one-shot apt + Node 20 + Rust stable
+ codeburn CLI + repo clone + npm install. Leaves the user one command
away from `npm run tauri dev`.
desktop/Scripts/autoinstall/: cloud-init user-data + meta-data plus a
README for building the CIDATA ISO. Mount that ISO alongside the Ubuntu
Server ISO in UTM and the installer runs without any prompts. Default
test credentials codeburn/codeburn; README calls out changing them for
non-throwaway VMs.
