Summary

• explain when to choose build-iterated-agentic-loop versus design-control-loop
• make the selection boundary visible in README, plugin metadata, and both skill entrypoints
• use goal, checker, selector, agent, external changes, and regression gate throughout design-control-loop while keeping control-theory names as an optional mapping
• update the example, prompt, memory, runner, and workflow templates to use the same plain-language vocabulary

Validation

• both skill directories pass skill-creator quick_validate.py
• marketplace and plugin JSON files parse successfully
• workflow-template.yml parses successfully
• git diff --check passes
• legacy control-theory terms remain only in the optional mapping section

Closes #2
