fix: remove stale server/ui-dist from git add in release.sh

The release script cleaned up temporary build artifacts (ui-dist, skills)
before staging files for the commit, then tried to git add server/ui-dist
which no longer existed.  Remove it from the git add list since these
artifacts should never be committed — they're only needed during publish.
