name: Security audit

# Scheduled advisory check against the committed Cargo.lock. PR/push CI
# (rust.yml) already runs the full `cargo deny check`, but new RustSec
# advisories can be published against an unchanged lockfile — this catches
# those without requiring a push. Licenses/bans/sources can only change with
# a lockfile change, so the scheduled job checks advisories only.
