ZenFile v2.1.2

✨ 新增功能

APK 打开方式可切换：设置 → APK 安装设置新增「APK 打开方式」，可在「内置安装器」与「系统选择器」之间切换。选择系统选择器后，ZenFile 不再强制拦截 APK 打开，InstallerX、InstallWithOptions 等第三方安装器可正常接管，批量安装无需再长按逐个选择「打开方式」。

「大小和间距」可调范围扩大：卡片间距滑块下限由 40% 放宽到 -50%，0% 时卡片边框紧贴、负值可让相邻卡片边框重叠成一条线；同时默认值改为 0%（新用户首次启动即贴边，已调整过的用户保持原值）。
自定义快捷方式弹窗：「图标形状」与「每行显示」由并排按钮改为下拉选择，布局更紧凑统一。

指纹解锁改为默认关闭：安装后「设置 → 安全设置」中的指纹解锁默认处于关闭状态，需主动开启，避免新装或升级后自动启用生物识别解锁。
修复 APK 安全扫描配置好 API Key 后、关闭再打开开关无法再次进入配置页重新配置 Key 的问题；现在开关打开与点击卡片均可进入配置页修改 Key。
修复「静默安装」在已授权 Shizuku 的情况下仍提示「权限不足」无法安装的问题：Shizuku 路径改用系统 PackageInstaller 会话安装，不再依赖被部分系统禁止的 shell 安装命令。

Switchable APK open method: Settings → APK Install Settings gains an "APK open method" option to choose between the built-in installer and the system chooser. With the system chooser, ZenFile no longer intercepts APK opening, so third-party installers like InstallerX and InstallWithOptions can take over normally — batch installs no longer require long-pressing each file to pick "Open with".

Wider "size & spacing" range: the card spacing slider now goes down to -50% (was 40%). At 0% cards sit flush; negative values let neighbouring card borders overlap into a single line. The default is now 0% (new installs start flush; users who already tweaked it keep their value).
Custom shortcut dialog: "icon shape" and "columns per row" are now dropdowns instead of side-by-side buttons, for a more compact and consistent layout.

Fingerprint unlock is now off by default: after install, fingerprint unlock under Settings → Security is disabled by default and must be turned on manually, so a fresh install or upgrade no longer auto-enables biometric unlock.
Fixed the APK security scan: once an API Key was set, turning the scan off and on again could not reopen the config page to change the Key. Now both toggling the switch and tapping the card open the config page to edit the Key.
Fixed "silent install" still reporting "permission denied" even when Shizuku was granted: the Shizuku path now uses the system PackageInstaller session install instead of the shell install command that some ROMs block.
