Scrum4Me/scripts/insert-milestone.ts

// Idempotent insert van één milestone (PBI + stories + tasks) uit de backlog.
//
// Gebruik:
//   npm run db:insert-milestone -- M8                       # standaard product SCRUM4ME
//   npm run db:insert-milestone -- M8 --product SCRUM4ME    # idem
//   npm run db:insert-milestone -- M8 --dry-run             # niets schrijven, alleen tonen
//
// Bron: docs/backlog/index.md (gecommit, single source of truth).
// Tweede keer draaien is veilig: bestaande PBIs/stories/tasks worden niet
// gedupliceerd. Sprint-toewijzing doe je apart via Sprint Planning in de UI.
