fix(core): architect must emit all 5 SECTION blocks even when expanded

Round 3 bench8 显示架构师被规则 7 (OKR 递归大纲) + 规则 8 (前台/后台故事分层)
撑胖后, 模型把 story_frame 和 volume_map 写很长, 写到大约 2400 汉字就停
了——没进 roles / book_rules / pending_hooks. parseSections 拿不到后三段
直接判 "Architect output missing required sections".

maxTokens 已经是 20480, 停早不是撞上限, 是模型自觉 "讲够了".

修复: 在中英两个 foundation prompt 末尾都追加 "硬性完结检查" 段, 直接写明
必须依次输出 5 个 SECTION 块, 哪怕 roles 只列 3 个角色、book_rules 是小
YAML、pending_hooks 只有 3 行也要写完. 不压缩规则 7/8 本身的内容量, 只是
把 "交付标准" 再打一次钉子.

顺手修一个 Edit 回合里错删的英文方法闭合大括号.

+You MUST emit all **5 SECTION blocks in order**: story_frame → volume_map → roles → book_rules → pending_hooks. Do NOT stop after story_frame or volume_map just because they ran long. Even if roles lists only 3 characters, book_rules is a tiny YAML block, and pending_hooks has only 3 rows, all five must appear. The output is only considered delivered after the last row of pending_hooks is written.`;
