docs(i18n): restore prompt-v4 as the pipeline baseline

按 jingtingxiang 拍板将 prompt 回到 v4 基线：模板正文恢复内嵌的
格式/语气/句式/词汇/标点全量约束与 11 组正误例（量词规则按术语表
现行裁定 package→包 写作「由三个包构成的 seam」），不再注入
translation-rules.md——该文件约束人和 agent，不进模板；占位符收敛
为 source_lang/target_lang/terminology 三个，切换行由模型按文档
自身拼写。渲染器、解析器、conformance 门禁与单测同步回 v4 契约：
三段裸 XML（translation/review/final 顺序唯一），容忍整体 ```xml
围栏回显；saxes 依赖随 CDATA 协议一并移除。
