Add cleo - dependency manager for Claude Code

[Surt]

What is cleo?

cleo is a dependency manager for the Claude Code ecosystem — npm / pip / composer for rules, skills, agents, commands, hooks, and MCP servers.

# As a Claude Code plugin (gets you /cleo-install, /cleo-require, etc.)
/plugin marketplace add https://github.com/Surt/cleo
/plugin install cleo@cleo

# Or as a standalone CLI
git clone https://github.com/Surt/cleo
cd cleo && pip install pyyaml

Why it fits this list

One cleo.json manifest installs and version-pins everything .claude/ needs across a team. Resolves vendor/name → github.com/vendor/name automatically. No registry signup. Lock file (cleo.lock) for reproducible installs across CI and developers.
