feat(agents,api): 一致性冲突一键采纳补丁对 original/replacement + SSE/契约透传

- Conflict schema 增 original/replacement（可缺）：可局部修复时审稿提议精确补丁
- 续审 prompt 指示填逐字 original + 改后 replacement，不可定位则留空
- orchestrator SSE conflict 事件 + apps/api ReviewConflictView 透传两字段
- 重生成 TS 客户端 schema.d.ts；memory/contracts.md 记录契约变更（向后兼容）
