阶段1工程化改造:npm 管理依赖,构建脚本自动压缩与拷贝运行时库

- 新增 package.json/scripts/build.js,npm run build 一键完成压缩与依赖拷贝
- hls.js(1.6.16)/flv.js(1.6.2)/mpegts.js(1.8.0) 由 vendored 改为 npm 依赖
- 删除 Source File/(PSD 与 Flash 遗留 crossdomain.xml)
- 新增 AGENTS.md 项目说明与改造路线图

+ * 功能：
+ *   1. 使用 terser 将 ckplayer/js/ckplayer.js 压缩为 ckplayer.min.js
+ *   2. 从 node_modules 拷贝运行时依赖(hls.js/flv.js/mpegts.js)到 ckplayer/ 对应目录
+ *      播放器运行时会按需动态加载这些文件,目录结构需与 getPath() 的约定保持一致
+ * 用法：npm run build
