feedback1 final: DESIGN §21 intro maps the closing additions (§21.25 PRs, §21.26-§21.29), §10 notes the draft's 本局禁用 mark

- DESIGN §21 intro: §21.25 now credits PR #2, #7, #10 and #14; the closing additions are mapped (issues #1 / #8 gaps
  §21.26, issue #5 / #8 item 5 client fixes §21.27, the draft's match info §21.28, the six 重装 skills' deliberate
  trigger deviation §21.29), the merge order names the four closing branches (their three "§21.26" subsections
  renumbered §21.26-§21.28 in merge order) and GitHub's master, and the normative lines they rewrote are listed.
- DESIGN §10: a strategy built around a switched-off bond carries the 本局禁用 mark in the strategy draft (§21.26).
- CHANGELOG 0.1.1 intro names the GitHub issues and pull requests handled.
- docs-consistency: §21.1-§21.29 present and numbered consecutively; the intro's new mappings.
