Shortcut: refactor

<!-- GENERATED by generate-profile/scripts/build-shortcut-skills.py from .aid/runtime/templates/shortcut-catalog.yml -- DO NOT EDIT BY HAND; edit the catalog row and re-run the helper, then the full run_generator.py. -->

Bind VERB=refactor, ARTIFACT="" (bare verb), then run the shared engine at .aid/runtime/templates/shortcut-engine.md. The engine scaffolds the flattened Lite work (feature-001 structure) and authors exactly two documents: REQUIREMENTS.md, whose § 11 feature section carries the technical specification and whose § 9 carries the gate criteria, and the task DETAIL.md files -- with reduced capture. One feature and one delivery means there is nothing to sequence, so no plan is written and the execution graph is derived from each task's **Depends on:** field. It runs the per-document Grading Gates (feature-004) and halts at the FR-10 approval gate. It never executes. This shortcut's default_type/group are its row in .aid/runtime/templates/shortcut-catalog.yml.
