// Hard delete mode: bypass tombstone TTL safety, use --older-than days directly

var cleanupCmd = &cobra.Command{
	Use:   "cleanup",
	Short: "Delete closed issues and prune expired tombstones",
	Long: `Delete closed issues and prune expired tombstones to reduce database size.

This command:
1. Converts closed issues to tombstones (soft delete)
2. Prunes expired tombstones (older than 30 days) from issues.jsonl

It does NOT remove temporary files - use 'bd clean' for that.

By default, deletes ALL closed issues. Use --older-than to only delete
issues closed before a certain date.

HARD DELETE MODE:
Use --hard to bypass the 30-day tombstone safety period. When combined with
--older-than, tombstones older than N days are permanently removed from JSONL.
This is useful for cleaning house when you know old clones won't resurrect issues.

WARNING: --hard bypasses sync safety. Deleted issues may resurrect if an old
clone syncs before you've cleaned up all clones.

EXAMPLES:
Delete all closed issues and prune tombstones:
  bd cleanup --force

Delete issues closed more than 30 days ago:
  bd cleanup --older-than 30 --force

Preview what would be deleted/pruned:
  bd cleanup --dry-run
  bd cleanup --older-than 90 --dry-run

Hard delete: permanently remove issues/tombstones older than 3 days:
  bd cleanup --older-than 3 --hard --force

SAFETY:
- Requires --force flag to actually delete (unless --dry-run)
- Supports --cascade to delete dependents
- Shows preview of what will be deleted
- Use --json for programmatic output
