migrate-v3

name	migrate-v3
description	Guided v2 to v3 backlog migration. Triggers: 'upgrade to v3', 'migrate to v3', 'switch to v3', 'enable handovers', 'enable narrative continuity'. Only correct way - do not call backlog_migrate_v3 directly without the pre-flight gate.

Migrate to v3

Follow the playbook at ../../playbooks/migrate-v3/playbook.md (relative to this skill's base directory). Read it in full and execute it exactly. references/ paths inside the playbook resolve relative to the playbook's own directory.
