CLI package handoff

packages/cli owns AgentsKit Chat application detection, safe file generation, and command UX.

• Reuse published AgentsKit/AgentsKit Chat packages in generated source.
• Never copy private upstream templates or overwrite a non-empty target.
• Keep CI non-interactive and diagnostics on stderr.
• The closed renderer matrix is React, React Native, Ink, Vue, Svelte, Solid, and Angular.
• Add each renderer to detection, templates, help/completion, golden, install, typecheck, and generated-test coverage together.
• add component owns contract/native file generation but never source-code registration or overwrite merging.
