Dataset: add READMEs, organize scripts, update .gitignore

- Add README.md to all 16 dataset directories with script references
- Centralize generation scripts under scripts/ with full README
- Update .gitignore to cover all data directories, keep only metadata
- Remove redundant CCPD/.gitignore (parent covers same rules)
- Remove stale scripts/test/ (254MB pipeline residue)
- Fix label parser reference: scripts are authoritative source of truth

# CCPD 真图 TRANS
| 项目 | 详情 |
|---|---|
| 来源 | 由 `CCPD/` 通过 GT 顶点透视变换生成 |
| 规模 | 296,838 张 |
| 生成脚本 | `scripts/sample_ccpd_full.py` |
| 标签格式 | 从原始 CCPD stem 编码解析(`parse_ccpd_filename`),**不依赖文件名后缀** |
| 训练用途 | OCR 三源混合训练数据源之一 |
> **以脚本为准**:文件名后缀中的标签可能不准确,实际标签由 `dataset.py` 中的 `parse_plate_suffix` 从原始 CCPD stem 解码。2026-06-23 已修复 AO→澳 误替换 bug。
