Scaffolds and revises apm instructions files, with a throwaway-package
verification recipe because `apm compile --validate` always exits 0 and
Claude Code drops `description`. Routed from forge and linked from
apm-workflow's compile reference. Bumps kyberforge to 2.1.0 and the catalog
to 0.5.2.
Fixes#148
