Captures the SHR-WP-0001-T01 residual: statehub register scaffolds
INTENT.md and a flavor-derived workplan prefix for prj- repos, both of
which the project-repository-flavor standard forbids.
Root cause: statehub_register.py has no reference to
.repo-classification.yaml, category, or repo_flavor anywhere, so it cannot
distinguish a project repo from a durable product repo.
Hit twice now (prj-state-hub-retirement, prj-canon-federation). T08 carries
the fix forward to repo-manager so it is not stranded in a component
scheduled for retirement.
