fix(saa): GAMEDEF_SYSTEM 加保真铁律 + breakout 异构 few-shot——修生成坍缩(bug#5)

根因:GAMEDEF_SYSTEM 仅内联 2 个 few-shot(躲避 + tap-targets 打地鼠)、
无 brief-fidelity 约束,模型对任何题面"挑最近的套"——动作类抄躲避、
点击类抄打地鼠,打砖块/贪吃蛇/射击全坍缩。

两处最小修(对齐根因 1+2):
1) 在三个参照前置【★保真铁律★】:参照仅示范结构与 rt 面用法、不是玩法清单;
   必须按题面产对应实体/行为/规则(给打砖块/贪吃蛇/射击/跑酷范例);
   严禁因参照是躲避/打地鼠/打砖块就把题面玩法坍缩成它们。
2) 内联【参照3·breakout】(挡板+球+砖墙+反弹消砖、清砖判胜、球落底判负),
   源自过门金样 contracts/agent-loop/skeletons/breakout.json,结构精简对齐 rt 面,
   与原 2 例并列、打破"只有躲避+打地鼠"偏置(三参照覆盖异构三形态)。

验证:① 三参照 JSON 均合法、顶层键齐(entities/components/behaviors/scenes/rules);
② 参照3 经 game-runtime createRuntime 真驱动跑通——砖墙24块/撞砖计分/消砖
remaining降/球落底 lose-latch/指针控板,全程零抛错;③ gd-archetypes.test 4/4 不回归;
④ aigc-server 离线编译通过(文本块转义合法)。

不重新生成游戏(重生验证由部署后另做)。
