feat: 深度完善 — 存根转真实实现、UI类方法补全、Java集合/IO增强
存根转真实实现: - ContentResolver: query/insert/update/delete对file://URI真实文件操作, getType用mimetypes - Context: getResources/getAssets/getString/getColor 委托真实Resources - Bitmap.sameAs: PIL像素比对 - Canvas: quickReject/drawTextOnPath/drawPicture/drawDoubleRoundRect 真实实现 - Paint: measureText/breakText/getTextWidths/getFontMetrics/getTextBounds 用PIL字体 - PathMeasure: 真实路径展平/长度计算/坐标切线提取 - Path.op/Region.op: 布尔运算 - Camera: 3D变换矩阵计算 - SystemClock.setCurrentTimeMillis: date -s命令 - Environment.isExternalStorageRemovable: /proc/mounts检查 - Process.myUid: os.getuid() - PowerManager.isPowerSaveMode: CPU governor检查 - Vibrator: Linux LED振动器设备支持 - FileObserver: 轮询线程检测文件变化 - SensorManager.getRotationMatrix: 完整旋转矩阵算法 - BatteryManager: LinuxPower真实电池数据 - Geocoder: Nominatim API逆地理编码 - LocationManager: addProximityAlert/setTestProviderLocation UI类方法补全: - TextView: setPaddingRelative/getTextColor/setBreakStrategy/setJustificationMode - ImageView: setColorFilter/getColorFilter/clearColorFilter - CheckBox/Switch: setOnCheckedChangeListener - ListView: clearChoices - ViewGroup: setLayoutTransition/setTouchscreenBlocksFocus/getChildVisibleRect - MotionEvent: getHistoricalX/Y/Pressure/EventTime/addBatch/getEdgeFlags/setAction Java集合增强: - ArrayList: spliterator/stream - HashSet: spliterator/stream/removeIf - TreeMap: replaceAll/compute/computeIfAbsent/computeIfPresent/merge - LinkedHashMap: clone (保留access_order) - PriorityQueue: spliterator/clone Java IO增强: - BufferedWriter: append/check - PrintWriter: append - ByteArrayOutputStream: writeTo - ByteArrayInputStream: markSupported - BufferedInputStream: available/mark/reset/markSupported + 修复_fill缓冲区填充bug - SequenceInputStream: 补全实现(Enumeration/多流/跨流聚合读取) 修复: - ViewGroup.addView: 合并重复定义为智能参数分派 - view_ext.ViewGroup: 继承view.ViewGroup - view_ext.KeyEvent: 继承view.KeyEvent - hardware_sensor_ext.SensorManager: 继承hardware.SensorManager - app_fragment: 使用java.lang.IllegalStateException - content_intent.Intent: setData/getScheme正确从Uri提取scheme - __init__.py: 补全Fragment/KeyEvent/MotionEvent/TrafficStats/RecyclerView/TreeMap/Vibrator等导出 统计: 221模块, 3662类, 30952方法, 182302行
