fix(install): install webkitgtk-6.0 runtime per distro, refuse on musl

The release binary dynamically links libwebkitgtk-6.0, which is not preinstalled on most distros and is not shipped in the tarball, so installs failed at first launch with a missing-.so error. Add a step-0 dependency stage to install_linux.sh that maps Arch/Debian-Ubuntu/Fedora/OpenMandriva/Void to their verified runtime package names (ID plus ID_LIKE, so derivatives resolve), requires root/sudo, and stays idempotent. musl systems (Alpine, Void-musl) get a warning plus hard-abort: the glibc-linked binary cannot run there and no package fixes that. Unknown distros get the package table and exit 1. Existing desktop/icons/binary steps untouched. Verified with an 11-case stub harness (all families route correctly; sudo/no-sudo/missing-manager/musl/unknown all behave).
