The job was gated with `github.repository == 'MadsLorentzen/ai-job-search'`
on top of the pull_request check, so it never ran on any fork -
including every adaptation listed in the community fork-index
discussion. The job already probes Dependency graph availability and
gracefully warns-and-passes when the graph isn't enabled, so the
repository-name gate wasn't protecting against a real failure mode -
it was just silently skipping vulnerability scanning everywhere except
this one repo. Removing it lets any fork with Dependency graph enabled
get real coverage, and costs nothing on repos where it isn't (the
existing probe already handles that gracefully).
