3.9.0

• Difficulty types can now give status effects to players (player_effects), optionally scaling with level
• Added No Mining status effect, slows down block breaking like Mining Fatigue, but leaves attack speed alone
• Player effects are opt-in, zones need "player_effects": true to give them
• Dungeon difficulty type comes with No Mining (level 2+), to prevent breaking blocks
• Blocks in #dungeon_difficulty:no_mining_exempt (spawners, cobwebs, sculk sensors and shriekers, torches, treasure blocks by default) break at normal speed under No Mining
• Custom status effect registration can be disabled in config/dungeon_difficulty/registry.json
