Open Parties and Claims compatibility

If Open Parties and Claims is installed and `openPartiesAndClaimsSupport` is enabled, Undead Riders checks OPAC claim settings before spawning a horseman.

Claims that have hostile natural spawning disabled, for example through OPAC's "Allow Hostile Spawn" setting, will block Undead Riders natural spawns in that claimed area.

🔄 Commands

Both commands require gamemaster permission (op level 2).

| Command | Description | |---------|-------------| | `/undeadriders reload` | Reloads the config from disk without a server restart | | `/undeadriders info` | Shows enabled/disabled status, spawn rates, and current caps in chat |

---

📦 Installation

1. Download the latest JAR. 2. Place the JAR in the `mods/` folder. 3. Make sure Fabric API is also installed. 4. Optional for claim protection support: install Open Parties and Claims on the server. 5. Optional for in-game config editing on the client: install Mod Menu and Cloth Config. 6. Start Minecraft — the config file will be created automatically.
