Skill Registry Lock

Later-tier scaffold for reproducible curated-skill registry locks.

Scope: Design placeholder only. Does not write lockfiles or run live sync.

Planned Workflow

1. Snapshot catalog index + authoring MDX install metadata.
2. Emit lock artifact for maintainer review (TBD path).
3. Compare dry-run drift against lock without applying installs.

Validation Contract

uv run python skills/skill-registry-lock/scripts/check.py
