feat: 大幅增强原生行为 — 修复P0 Bug + 补全核心API

P0 Bug 修复:
- Canvas.drawBitmap 重复定义导致重载丢失 → 合并为*args重载
- String.hashCode() 不可达的第二return → 修复为单return
- File.compareTo() 调用不存在的__cmp__ → 改为显式比较
- HashMap.remove() 逻辑错误 → 区分单参(返回旧值)/双参(返回boolean)

P1 核心行为增强:
- Handler: sendMessage/sendMessageDelayed 现在真正入队异步执行
- Looper: loop() 实现真正的消息循环(按when时间取出到期消息)
- AsyncTask: execute() 在后台线程池执行,完成后主线程回调
- Bundle: 新增12个数组类型put/get方法
- Math.round: 改为Java语义(floor(a+0.5))而非Python银行家舍入
- Thread: currentThread()缓存对象, 新增join/getState/getId/getPriority
- String: 新增strip/repeat/isBlank/lines/subSequence/getChars/chars/formatted/translateEscapes

P2 缺失API补全:
- 新增21个Java标准Exception类 (NullPointerException等)
- View: 新增39个事件处理/监听器/位置尺寸方法
- Activity: 新增33个生命周期/权限/UI方法
- Context: 新增22个文件流/权限/资源/主题方法
- Canvas: 支持 Canvas(Bitmap) 构造函数重载
- __init__.py: __all__ 补全Exception体系和Activity类
