fix: 改用actions/setup-java@v4从Temurin下载JDK25，彻底绕开服务器JDK探测和sdkman冲突

fix: 彻底绕开sdkman，直接用/usr/lib/jvm最高版本JDK，JAVA_HOME写入GITHUB_ENV并强制export到PATH
fix: 改用<release>25替代<source>/<target>，确保JAVA_HOME正确传递到Maven步骤

+
+### 验证码系统实现
+- ChatFilterManager 新增 VerificationResult 枚举(NEED_VERIFICATION/PENDING/VERIFIED/FAILED)
+- 新玩家首次发消息时触发数学题验证码(10以内加减乘除,随机选择)
+- 30秒有效期,答错/超时/非数字答案 → 吞噬消息
+- 答对 → 插件代为广播缓存的原始消息(无前缀,像普通聊天一样)
+- 老玩家(注册>1小时)快速验证后自动放行
+- pendingMessages Map 缓存未验证消息,验证通过后广播
+
+### 全场景链接过滤
+- 告示牌(onSignChange): 已有的 filterLinkInContent 拦截
+- 编辑书(onPlayerEditBook): 通过反射调用 getNewBook() 获取书页内容(兼容Paper 1.21.4)
+- 私信(onPrivateMessage): 新增 PlayerCommandPreprocessEvent 拦截 /tell /msg /w /r 命令中的链接
+
+### 编译部署
+- Maven clean package 编译通过
+- 推送到 git.ypshidifu.cn (main 分支)
+- JAR 上传到 SFTP 服务器
+- PHP 文件上传到 FTP /plugin/ 目录

+### 2.2.2 挂机白名单.txt
+当挂机踢出开启时，该配置下的玩家不受挂机提出影响
+
+### 2.2.3 SMTP设置.txt
+
+此文件控制着SMTP邮件服务器的配置，用于找回密码时发送邮件。<br>可通过GUI进行配置，也可以手动修改此配置文件。修改后，重载插件即可生效

+
+### 2.2.4 插件设置.txt
+
+此配置管控这整个插件，包括玩家能注册多少个账号、默认的管理员面板密码多少、tag包含什么视为管理员等
+
+```txt
+# ===== Sdf1_login 插件设置 =====

+
+### 2.2.5 chat.txt
+该文件控制着聊天过滤，当玩家发送违规链接时，会自动根据配置规则进行处理。<br>
+可用的处罚规则：
+- warn: 警告
+- mute: 禁言
+- kick: 踢出
+- ban: 封禁
+- banip：封禁IP
+
+```txt
+# Sdf1_chat 聊天过滤配置
+通知管理员: true
+全服通报: true

+### 2.2.6 radio_config.txt
+```txt
+# ============ Sdf1 Radio Config ============
+#
+# resource-pack-url
+#   填外部地址（HTTP或HTTPS均可）
+#   例: https://example.com/radiopack.zip
+#   留空 = 使用内置HTTP服务
+#
+# http-port
+#   内置HTTP端口（仅resource-pack-url为空时生效）
+#
+# ============ Settings ===============
+
+resource-pack-url=https://*.ypshidifu.cn/|*.mcserver.ccwu.cc
+http-port=443
+```
+- radio_config这里可以使用通配符域名，当使用通配符时，系统随机生成url，拒绝过资源包的玩家，每次都会收到提示。并且自1.2版本起，拒绝资源包=放弃游玩服务器。如果您无需广播功能，可以不放ogg文件进入`./plugin/radio/ogg`。这样服务端不会自动生成资源包，也不会强制下载了
+
+### 2.2.7 菜单.txt
+- 自定义菜单配置文件
+
+```json
+# 服务器菜单

+### 2.2.2 挂机白名单.txt
+当挂机踢出开启时，该配置下的玩家不受挂机提出影响
+
+### 2.2.3 SMTP设置.txt
+
+此文件控制着SMTP邮件服务器的配置，用于找回密码时发送邮件。<br>可通过GUI进行配置，也可以手动修改此配置文件。修改后，重载插件即可生效

+
+### 2.2.5 chat.txt
+该文件控制着聊天过滤，当玩家发送违规链接时，会自动根据配置规则进行处理。<br>
+可用的处罚规则：
+- warn: 警告
+- mute: 禁言
+- kick: 踢出
+- ban: 封禁
+- banip：封禁IP
+
+```txt
+# Sdf1_chat 聊天过滤配置
+通知管理员: true
+全服通报: true
+禁言时长: 300

+### 2.2.6 radio_config.txt
+```txt
+# ============ Sdf1 Radio Config ============
+#
+# resource-pack-url
+#   填外部地址（HTTP或HTTPS均可）
+#   例: https://example.com/radiopack.zip
+#   留空 = 使用内置HTTP服务
+#
+# http-port
+#   内置HTTP端口（仅resource-pack-url为空时生效）
+#
+# ============ Settings ===============
+
+resource-pack-url=https://*.ypshidifu.cn/|*.mcserver.ccwu.cc
+http-port=443
+```
+- radio_config这里可以使用通配符域名，当使用通配符时，系统随机生成url，拒绝过资源包的玩家，每次都会收到提示。并且自1.2版本起，拒绝资源包=放弃游玩服务器。如果您无需广播功能，可以不放ogg文件进入`./plugin/radio/ogg`。这样服务端不会自动生成资源包，也不会强制下载了
+
+### 2.2.7 菜单.txt
+- 自定义菜单配置文件
+
+```json
+# 服务器菜单
