fix: prevent gstack-relink from double-prefixing gstack-upgrade

Browse Source 
gstack-relink now checks if a skill directory is already named gstack-*
before prepending the prefix. Previously, setting skill_prefix=true would
create gstack-gstack-upgrade, breaking the /gstack-upgrade command.

Matches setup script behavior (setup:260) which already has this guard.
