feedback7 G-SMALL: co-op rooms can make AI teammates draft last (PR #368 by @anAtheist987)

Applied the host-only room option 「AI 队友最后选择」, default off. Off, the draft order and the random streams stay as they are. On, humans draft before AI seats after the existing shuffle, and a skip stays ahead of the AI seats.

Dropped docs/history/0.2.2.md and every §27 citation. The player-facing sentence is in docs/PLAYING.md. The room-option rule is in docs/design/match.md, docs/design/client.md and docs/design/network.md. The #338 per-bot faction and ban presets are not included.

Tests: node --test test/lobby-ai-last.test.js test/match/ai-picks-last.test.js test/ui/ai-picks-last.test.js — 18 pass. node --test test/lobby.test.js test/client-static.test.js — 378 pass. node tools/i18n.mjs check --all --strict — 1032/1032 in en, ja, ko and zh-TW, 0 errors.
