- 新增 shelf_model.c/.h：扫描/行序列从 shelf.c 拆出（纯 C，宿主可测）；shelf_book 加 group[96]（相对 Books/ 的目录路径，根下空串），path 语义/内容完全不变（进度键仍为 rdprog_hash(path)） - folder 模式：目录段头（根下=未分类），未分类置顶、其余按目录名排序；组内沿用最近阅读优先/其次书名；空目录不产生段头 - format 模式逐行保持旧行为；新增 reader.conf ui.shelf_group，缺键默认 format - 上限 256→2048（SHELF_MAX_ROWS=2N=4096，段头≤书数），超限置可读提示，不再静默截断 - 顶栏加「目录/格式」切换，设置页加「书架分组」；UTF-8 安全截断长中文目录名 - 单测 test/shelf_group_smoke.c（38 断言）+ 计时 test/shelf_scan_bench.c - build_reader.sh：链 meow_ui.a 解析冒烟 stbi_*；无 qemu 时跳过执行而非失败
