fix(fork): link published packages to the fork repo

Published packages weren't appearing in the fork's Packages view because
their repository.url still pointed at upstream (pascalorg/editor) — the source
is kept identical to upstream and the scope-rewrite only touches @pascal-app/
tokens. GitHub Packages couldn't associate them with the fork, so they landed
unlinked under the account.

Rewrite repository.url in the packed artifact to ${GITHUB_REPOSITORY} (the
publishing fork) so GitHub links the package to this repo. Source stays
untouched; works for any fork/scope since it reads the repo from CI.
