Skills dropped from sync — 16 sig drift

[github-actions]

Tracking catalog skills that were dropped or reverted by the last sync run. Failure modes surfaced here:

1. Missing artifacts — SKILL.md exists on the source repo but one or more required companions don't:
   • skill.oms.sig (NVIDIA detached signature)
   • skill-card.md (skill metadata card)
   • evals.json (eval definitions — anywhere within the skill directory)
2. Signature drift — files in the skill dir were updated on the source repo, but skill.oms.sig wasn't refreshed alongside. Loading this content would break crypto verification, so:
   • Skills that previously existed on main are reverted to their last-signed version (the signed copy stays live).
   • Brand-new skills with drift are dropped outright.
     Recovery: comment /nvskills-ci on a follow-up PR on the source repo so the next sync picks up a fresh, content-aligned signature.
3. Signature mismatch — the source repo delivered a refreshed skill.oms.sig, but the skill's content does not hash-match it. The source repo is internally inconsistent (skill files edited after the signing run, or a pipeline ordering fault). Same revert/drop handling as drift.
   Recovery: re-run /nvskills-ci at source and do not modify skill files after the generated signature commit lands.
4. Signature missing — source skill dir has no skill.oms.sig at all (never signed, or sig deleted upstream):
   • Previously-signed catalog skills are reverted to their last-signed version.
   • New unsigned skills are dropped outright.
     Recovery: run the signing flow on the source repo so skill.oms.sig lands alongside SKILL.md.
5. Orphan product dirs — product folder under skills/ with no SKILL.md inside (e.g. every skill was dropped, leaving only helper files).

Owners: re-run /nvskills-ci on the source repo after editing skill content so the signature stays in sync. This issue auto-updates each sync and closes when all skills are compliant.
