feat: 第三轮深度完善 — SQLite/JSON/网络/媒体/文本 真实实现

SQLite真实数据库:
- SQLiteDatabase: execSQL/insert/insertOrThrow/replace/update/delete/query 用sqlite3
- 修复getVersion/setVersion用PRAGMA user_version
- 修复getMaximumSize/getPageSize/setMaximumSize/setPageSize用PRAGMA
- SQLiteStatement: execute/simpleQueryForLong/simpleQueryForString/execQuery
- SQLiteOpenHelper: onCreate/onUpgrade/onDowngrade回调正确触发
- 修复SQLiteCursor.moveToPosition越界处理
- 修复ContentValues值对提取bug

JSON真实实现:
- JSONObject: isNull/append/putOnce/putOpt/getNames
- JSONArray: 完整put/get/opt/length/toString

网络真实实现:
- NetworkInterface: getByName/getNetworkInterfaces/getHardwareAddress 用/sys/class/net+fcntl.ioctl
- InterfaceAddress: 新增类
- ConnectivityManager: getActiveNetwork/getAllNetworks 用LinuxNetwork
- WifiManager: getScanResults用nmcli, setWifiEnabled用nmcli/rfkill
- BluetoothAdapter: getAddress/getName 用bluetoothctl

媒体真实实现:
- MediaPlayer: prepare检查文件, getCurrentPosition实时计算, getDuration/getVideoWidth用ffprobe
- MediaRecorder: setVideoSize/setVideoFrameRate/setVideoEncodingBitRate配置存储
- MediaMetadataRetriever: extractMetadata用ffprobe, getFrameAtTime用ffmpeg, getEmbeddedPicture用ffmpeg

文本真实实现:
- TextUtils: split用re.split, concat/indexOf/lastIndexOf/urlEncode/urlDecode
- SpannableString: setSpan/getSpans/getSpanFlags/nextSpanTransition 真实实现
- SpannableStringBuilder: 修复append重载bug

Provider增强:
- Settings: putBoolean/getBoolean
- MediaStore: getContentUri/VOLUME常量
- ContactsContract: 补全常量和CommonDataKinds

Util增强:
- Log: w/e/wtf支持Throwable参数, 修复wtf重复定义bug
- TypedValue: 修复complexToDimension/complexToFloat/getFloat实现

修复:
- __init__.py: 补全NetworkInterface/InetAddress/MediaMetadataRetriever/SpannableStringBuilder导出
