• src/dm20_protocol/storage.py:508-527 (handler)

  The `DnDStorage.list_campaigns` method iterates through the campaign storage directory, detecting both legacy monolithic files and new split-format directories to return a sorted list of campaign names.

  def list_campaigns(self) -> list[str]:
      """List all available campaigns (both monolithic and split formats)."""
      campaigns_dir = self.data_dir / "campaigns"
      if not campaigns_dir.exists():
          return []
  
      campaigns = []
  
      # Find monolithic campaigns (JSON files)
      for f in campaigns_dir.glob("*.json"):
          campaigns.append(f.stem)
  
      # Find split campaigns (directories with campaign.json)
      for d in campaigns_dir.iterdir():
          if d.is_dir():
              campaign_file = d / "campaign.json"
              if campaign_file.exists():
                  campaigns.append(d.name)
  
      return sorted(campaigns)
