Agent Skills: plugin-parity-drift

This skill should be used to check whether any Lisa-native reimplementation of a curated third-party Claude plugin has drifted behind its upstream version. It wraps the deterministic detector at scripts/plugin-parity-drift.mjs, which scans `synced-from`-stamped SKILL.md files, resolves each plugin's current upstream version from the installed plugin cache, and reports stale/ahead/missing pins via a CI-gateable exit code. Use it in CI, before a release, or any time the curated plugin set is updated. It only reports — it never edits a skill or auto-bumps a pin.
