Better Difficulty

🌕 Added a brand new Blood Moon spawn system (BloodMoonSpawner) running alongside vanilla spawning. 🩸 Added new Blood Moon schedule modes:

chance nth_night full_moon ⚙️ Added new blood_moon config options in config/betterdifficulty/difficulty.json:

schedule_mode nth_night spawn_whitelist spawn_blacklist mobs_drop_loot 🏷️ Added a runtime tag for mobs spawned by Blood Moon: bd_bloodmoon_spawned.

Changed 🔧 Reworked Blood Moon from the old spawn-duplication model into a dedicated custom spawner. 🌌 Changed surface_spawn_only default value to false for behavior closer to Lumien Bloodmoon. 🚫 SPAWN_BLOCKER is now bypassed while Blood Moon is active. ♻️ /betterdifficulty config reload can now immediately stop an active Blood Moon if blood_moon.enabled is set to false.

Fixed 🛠️ Unified Fabric and NeoForge behavior for Blood Moon anti-farming loot handling. ✅ Improved Blood Moon schedule stability and added stronger tests for nth_night, full_moon, and scheduled starts. 🧪 Added tests for whitelist/blacklist spawn filtering and surface_spawn_only behavior.
