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
