🟡 [M19] benchmark report variant 列顺序依赖输入顺序

已修复，提交 a8b64e7。

修改内容：

  1. Latency 表列顺序 — variants 去重改用直接 tuple 比较取代 format! 字符串比较，构建后 sort() 确保稳定字典序
  2. Memory 段行顺序 — 按 (test_name,…

🔴 [H3] scroll_during_append 使用过期 PreadReader 导致增长文件 benchmark 失真

修复方案

根因: PreadReaderCore 在 open_raw 时一次性构建 LineIndex，file_size 和 total_lines 之后永不更新。get_line_impl 对 idx >= total_lines 直接返回 None，导致 benchmark…

🔴 [H4] 大文件生成未使用 BufWriter 导致 benchmark 数据准备极慢

Fixed in 6dd87d2.

Root cause: writeln! directly on raw File — each line (~70 bytes) triggered a separate write syscall.

Fix: Wrapped all three write-heavy functions with BufWriter::with_capacity…
