The root-run package hook changed ownership of paths below a user-controlled home directory. A config symlink could redirect chown to an arbitrary root-owned file during installation or upgrade. Run the config writer as the target desktop user and remove the privileged ownership changes. This also prevents the missing-config path from writing through a user-controlled pathname as root. Add regression coverage and bump the package release.
