feat(spec)!: 双源清账 C13+C15 —— 退役 L1「Simple Sync」整层,integration 冲突枚举改名 ConnectorConflictResolution,ui 侧保名 (#4738)

`DataSyncConfig(Schema)` 曾由 `./automation` 与 `./integration` 各导出一个声明,
`ConflictResolution(Schema)` 三个入口三个声明(#4411 陷阱)。按维护者裁决
(#4535 前锋判定 + 2026-08-03 批复,L1 否决位默认通过)三动作一单:

- **automation 侧整体死删**:`automation/sync.zod.ts` + `sync.test.ts`(L1
  「Simple Sync」层,17 个导出名)。三仓(objectstack / cloud / objectui)
  import 语句级零消费者、无父 schema 嵌入,8 个 def 全部不再发出 ——
  39 个 authorable key 删行由 #4650 门禁按路径 3(整 def 消失)自证,
  归 manifest ratchet(#2978 蓄意移除,8 键逐个列于 PR)+ check:api-surface
  管辖。
- **integration 侧 D9(a) 改名**:`ConflictResolution(Schema)` →
  `ConnectorConflictResolution(Schema)`,走 `RENAMED_DEFS` 承接(0-key carry,
  枚举值逐字不变);`DataSyncConfig` integration 侧保名不动
  (`ConnectorSchema.syncConfig` 活解析路径)。
- **ui 侧保留正名一字不动**:objectui `useOffline.ts` + `types/index.ts:1054`
  re-export + parity ratchet 钉住;`api/ConflictResolutionStrategy` 第四亲戚
  未动。

- dual-source-exports.baseline.json:删 4 行(认领时点账面 12 → 8;C16 #4752
  先行合入 −2,rebase 到 5647006 后实跑 10 → 6)
- 回归 pin(sync-retirement.test.ts):compiler-API 符号身份 + exports-map
  全入口枚举 + 唯一属主断言 + 防空转守卫;S1(重加导出)/ S2(禁止的裸名
  re-export 收敛)/ S3(动 ui 侧名字)三组 sabotage 均红后还原
- SYNC_ARCHITECTURE.md:三层 → 两层 + 显式 L1 退役记录;PROTOCOL_MAP /
  quick-reference / etl.zod / connector.zod / shared/mapping.zod 头注连带更新
- expression-conformance.ledger.ts:删 stale cover(automation/sync.zod.ts:condition)
- 严格性台账:automation 86 → 74 sites(check:strictness-ledger 实跑)
- changeset:@objectstack/spec major(TS2305),零元数据迁移(integration 值域
  逐字节不变;automation 侧无解析站点即无作者,conversion 不可达)

+BREAKING(spec): 退役 L1「Simple Sync」整层(`@objectstack/spec/automation` 的 `DataSyncConfig` 一族,17 个导出名),并把 `@objectstack/spec/integration` 的冲突策略枚举改名 `ConflictResolution` → `ConnectorConflictResolution`;裸名 `ConflictResolution` 现在全包唯一地指 `@objectstack/spec/ui` 的离线同步概念 (#4738, #4535 C13+C15)
+
+`DataSyncConfig(Schema)` 曾由 `./automation` 与 `./integration` 各自导出一个声明,`ConflictResolution(Schema)` 更是**三个入口三个声明**(#4411 陷阱):

+| `DataSyncConfig` | `./integration`(**保名不动**) | 9 键,direction=import/export/bidirectional,batchSize 默认 1000 | 唯一真源(`ConnectorSchema.syncConfig` 活解析路径) |
+| `ConflictResolution` | `./automation`(**删除**) | `destination_wins` / `merge` 等 5 值 | 随 L1 整层退役 |
+| `ConflictResolution` | `./integration`(**改名**) | `target_wins` 等 4 值 | → `ConnectorConflictResolution(Schema)`,枚举值逐字不变 |
+| `ConflictResolution` | `./ui`(**一字不动**) | `client_wins` / `server_wins` / `manual` / `last_write_wins` | 裸名唯一归属(objectui 实活消费) |
+
+**automation 侧是叙事层,不是实现**:L1「Simple Sync」只存在于 `SYNC_ARCHITECTURE.md` 的三层故事里 —— 三仓(objectstack / cloud / objectui)import 语句级零消费者,没有任何引擎解析或执行过 `DataSyncConfig`,8 个 def 从元数据根真 Zod 图不可达(#4650 门禁实测)。整文件删除:`DataSyncConfig(Schema)`、`ConflictResolution(Schema)`、`SyncDirection(Schema)`、`SyncMode(Schema)`、`DataSourceConfig(Schema)`、`DataDestinationConfig(Schema)`、`SyncExecutionStatus(Schema)`、`SyncExecutionResult(Schema)`、`Sync` 工厂。
