feedback7: merge fb7-stats — the local statistics page (PR #323 by @2321Robin, reworked): a match counts when it reached its result or the player cleared at least one round before quitting; earlier quits stay in the history marked 中途退出 / 不计入统计 (the owner's rule of 2026-10-08)

- Conflict: docs/PLAYING.md — #321's §12 反馈问题 and the stats §12 both added; the stats section is §13 (README anchor
  updated).
- Golden unchanged; broad node --test 5382 (5381 pass, 0 fail, 1 skipped); lint 0 errors.
