feat(DLD154V4B): V2.9 平坦性离开判定默认关闭（现场实测不理想）+ 全量文档同步

Browse Source 
- TaskLoop.h: USE_FLATNESS_EXIT 1→0，离开判定切回简单滞回 3 次防抖
  (与 DLD154Pro 一致)；平坦性代码保留 #if 内可一行开启
- technical-spec: 模式1标默认(V2.9起)/模式2标禁用；修正模式1伪代码
  方向错误(CAPVD<Origin+dlt → (Origin-dlt)<CAPVD)；延迟/误检率表同步
- product-manual/release-notes: 离开判定口径改'滞回+连续确认(平坦性可选)'，
  最高档灵敏度 0.015%→0.031%(V2.8 残留)；版本历史补 V2.7/V2.8 缺行
- roadmap: V2.6→V2.9 行更新 + 突破表离开判定
- devlog: 置顶 2026-08-28 条目（背景/决定/同步清单）
