chore(reui): update documentation and component references to reflect new 20 building blocks

Updated the ReUI documentation to reflect the addition of three new components, bringing the total to 20. Adjusted descriptions, examples, and rules across various files to ensure consistency with the updated component list. Enhanced the API references and installation instructions to improve clarity for users.

This change includes updates to the SKILL.md, cli.md, components.md, registry.md, and workflow.md files, ensuring all references are accurate and up-to-date.
