补充提交

新增 AutofillBridge.java：隐形原生 EditText（低透明度伪可见）设置 autofillHints，支持填充建议与保存提示，commit 采用反射调用规避符号解析问题

新增 AutofillBridge.cs：拦截 InputField 点击改由原生框承接输入，屏幕坐标换算、文本实时同步回显；登录邮箱/密码框接入

登录点击时先 commit 触发保存密码再隐藏；失焦/键盘完成时软隐藏（视图保留树上供快照采集），hide 防重入修复 NPE；proguard-user.txt 添加 keep 规则防 R8 剥离

状态：待真机验证填充与保存提示，已加 autofill 会话诊断日志
