Android v0.6.2

Mobile maintenance release for encrypted connections.

• Keep paired devices on the trusted App interface when navigating back, preventing a return to a legacy Hub page that makes encryption appear disconnected. (#429)
• Consume terminal toolbar touch taps so Enter confirmation does not trigger the WebView default focus action. Keep explicit keyboard controls and existing Enter submission. (#430)
• Show the bundled frontend release identifier instead of dev in Settings. (#428)

Install the arm64-v8a APK on modern Android phones. Update over the existing installation to retain App data. Encrypted connections use the bundled interface, so these fixes require an App update.

中文：修复 Enter 等工具栏按键触摸时可能重新唤起键盘的问题；修复配对后返回旧 Hub 页面、加密状态看似消失的问题；修复 Settings 中 Frontend build 显示 dev。直接覆盖安装，无需卸载。
