feat: ddddocr-rs 完成 core/ort/tract2 规范整改与发布

准备

  - core：内置官方字符集（OLD/BETA）与 ModelMetadata::from_builtin_*
  构造器
  - ort：导出 Session、实现 Info、修正 cuda feature 接线、共享推理工具
  - tract2：包名更名（原 ddddocr-tract 已被占用）并完成规范整改
  - 集成测试按领域拆分（ocr / det / slide / common / api_surface）
  - 发布准备：Cargo.toml 元数据、workspace 版本 0.2.4、LICENSE/
  NOTICE、README 模型下载说明
