UZE, the official UZE plugin

This is a normal Agent Plugins 1.0 package. It carries no special treatment in the Store, the router, or any integration: it is installed, discovered and delivered exactly the way any other Skill-only package is.

It ships four Skills:

• skills/init/SKILL.md: an agentic orchestrator that calls UZE's own deterministic uze agent context inspect|plan|reconcile CLI to make a project's instructions context portable.
• skills/worktree/SKILL.md: coordinates isolated worktrees for concurrent agent work and safe integration, honouring the workspace: policy the project declares in agents.yaml.
• skills/architect/SKILL.md: writing the Mermaid diagrams a project keeps under workspace.artifacts: which view a change belongs in, how the architect surface lists it, and uze agent artifacts check as the proof it draws.
• skills/author/SKILL.md: creating a plugin end to end, from choosing or creating its marketplace to checking, installing and iterating on it.

The plugin format (skills, agents, MCP servers, hooks, and the ${PLUGIN_ROOT} placeholder) and what each harness receives are documented at uze.sh/docs/reference/plugin-format and uze.sh/docs/reference/harnesses.

See docs/capabilities/context-manager.md for the architecture these sit on top of, and docs/capabilities/uze-skill.md for how they are invoked per harness, the no-special-treatment proof, and what is not tested.
