Convert the simplest core task (review-adversarial-general.xml) from
type:task XML format to type:skill markdown format. This establishes
the pattern for converting remaining XML tasks to self-contained skills.
- Convert XML task to workflow.md with frontmatter, role, execution steps
- Add type:skill manifest for verbatim directory copying
- Extend manifest-generator getTasksFromDir to recurse into subdirectories
and detect type:skill entries (mirrors existing workflow skill detection)
- Update cross-references in quick-dev-new-preview, quick-dev, quick-spec
- Update module-help.csv to use skill: prefix
