更新内容

• 修复部分发行商（如 Corretto 四段式版本号）与安装后 release 文件版本格式不一致时，Java 更新完成后重新扫描仍提示有更新的问题。

• GUI 与 NoGUI 同步升级到 3.1.4；GraalVM 区分与 Minecraft 版本匹配逻辑保持不变。

Update Content

• Fix update detection reporting phantom updates after a Java runtime was already updated, caused by vendor version format differences (for example Corretto four-part versions versus the installed release file text).
• Cloud updates now compare the installed build with the latest cloud build first and skip the download entirely when the runtime is already current.
• After an update renames the Java folder to the new version, the registry entry name is rebuilt from the new version instead of keeping the stale one.
• The download page Minecraft advice adds a compatibility verdict and a quick Java-to-Minecraft mapping, plus reverse lookup of recommended Java majors for a Minecraft version.
• NoGUI scan without arguments now scans common Java install roots, matching the desktop behavior.
• NoGUI set-default on Windows falls back to the current user environment variables when administrator rights are unavailable.
• The GitHub mirror list gains an extra fallback mirror for better download success on weak networks.
• Smaller packages: desktop builds now embed only the tray dependencies of their own platform, and NoGUI builds no longer bundle tray dependencies at all.
• Removed the standalone desktop changelog page; release notes are now read from the GitHub Release page.
• GUI and NoGUI are both updated to 3.1.4; GraalVM edition separation and Minecraft matching behavior are unchanged.
