- migrations/019: programs table (slug PK, matching assessment_definitions/cohorts
convention), family (init/compile/root) and delivery_mode (self_paced/cohort/hybrid) as real
CHECK-constrained enums, versioned like assessment_definitions so an edit to
curriculum_path/delivery_mode never silently changes what an existing enrollment means. Seeds
exactly one program wrapping the existing RootNode/Kubernetes curriculum and capstone — no
new curriculum content invented.
- programs.js: list/get/create/update, with automatic version bump only when a
snapshot-relevant field actually changes.
