Usage: scripts/log-dep-audit-matrix.sh

Logs dependency audit entries for a small matrix of Cargo feature surfaces.
Each surface is deduplicated independently through scripts/log-dep-audit.sh.

Environment:
  MIRROR_LOG_DB       Database path to use. Defaults to ./mirror.db
  MIRROR_LOG_PREFIX   Source prefix. Defaults to dep-audit
  DEP_AUDIT_SURFACES  Newline-delimited matrix entries. Defaults to:
                      default|
                      embedding|--features embedding

Each DEP_AUDIT_SURFACES entry is:
  label|cargo tree args

Examples:
  scripts/log-dep-audit-matrix.sh

  DEP_AUDIT_SURFACES=$'default|\ninference|--features inference' \
    scripts/log-dep-audit-matrix.sh
