Creates migration to detect orphaned child issues and logs them for user
action. Orphaned children are issues with hierarchical IDs (e.g., "parent.child")
where the parent issue no longer exists in the database.
The migration:
- Queries for issues with IDs like '%.%' where parent doesn't exist
- Logs detected orphans with suggested actions (delete, convert, or restore)
- Does NOT automatically delete or convert orphans
- Is idempotent and safe to run multiple times
Test coverage:
- Detects orphaned child issues correctly
- Handles clean databases with no orphans
- Verifies idempotency
