JoinSuite v2.9.0

• 恢复纯 Spigot 支持：启动时自动检测服务端类型——Paper 系（Paper/Purpur/Pufferfish）走原生 Adventure API，纯 Spigot 自动切换旧式兼容 API，全功能可用
• 屏蔽名单：SQLite / MySQL 存储，UUID + 大小写保留玩家名，改名自动同步

• Plain Spigot support restored: the server type is detected at startup — Paper-family servers use the native Adventure API, plain Spigot automatically falls back to legacy APIs, all features work on both
• Mute list: SQLite / MySQL, UUID + case-preserved names, rename sync,.
