Fcmam5/skilleton

Implements deterministic dependency management for AI skills using git-backed manifests and lockfiles, similar to npm's package model but with zero registry dependency. Skills are resolved and installed directly from git repositories via `git ls-remote`, with full commit pinning to ensure reproducible team installations while respecting local git credentials for private repos. Includes introspection commands like `describe` to inspect skill metadata and structure, plus validation tooling to verify skill integrity.

Available on npm.
