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.

 Platform additions (implemented): `welcome.{resumed, version}`, `welcome.diyKitted` (0.2.0: the operators a 自选 slot may field — server/sim/content/kits/index.js `KITTED_CHARS`, the picker's list), `room.state.inMatch`, `error.detail`; `room.closed.reason ∈ 'timeout'|'kicked'|'empty'|'shutdown'` (`kicked`: room.kick / room.removeSpectator; `empty`: a spectator whose room lost its last player); WebSocket close codes 4001 (session taken over by another socket — client must not auto-reconnect), 4002 (no hello in time), 1008 (flooding), 1001 (shutdown). The host's `room.start` counts as the host being ready. After any (re)`hello` the server pushes `room.state` and, if a match runs, the match resends `m.public`/`m.private` (+`m.field`, or the field's `b.start` under client-side combat). **Reconnect window:** a dropped session stays resumable for 10 min (`net.js NET_DEFAULTS.reconnectWindowMs`; co-op seats keep playing their last lineup meanwhile, §6.6); a session that drops while its **solo** room's match runs stays resumable for the official `config.constants.singleReconnectTime` (86 400 s = 24 h; lobby option `soloReconnectWindowMs`; research 01 §1 "24小时内随时返回") — the untimed solo run simply waits. Only when the window expires does the drop become `match.onLeave` (co-op: 中途退出 = elimination; solo: the run ends `'abandoned'`). The client keeps its token in sessionStorage plus a recent-token list in localStorage, so reopening the tab resumes. Everything lives in server memory: a server restart ends every room and run. The lobby⇄match interface (constructor opts, `start/handle/onDisconnect/onReconnect/onLeave/dispose`) is documented verbatim at the top of `server/match/Match.js` and is normative. `server/data.js` provides `getData()` + index getters (`getChess`, `getBond`, `getGarrison`, `getItem`, `getBand`, `getEffect`, `getEnemy`, `getWave`, `getStage`, `getBoss`, `getToken`, `getConfig`, `getMode`). Note: the skill trigger rule lives at `chess.skill.trigger.rule` in data.
