chore(release): bump to v0.7.12 — 适配 kimi-code 0.40.1（flag 清单/优先级/危险命令守卫）+ WebUI 竞态修复 + models-dev 7495/212

- flag 清单 9→10：新增 file_history、search_worker；secondary-model
  0.40.1 起默认开启（defaultEnabled）
- env 探测补齐为 12 项元组（10 flag + master + legacy），修正此前
  tower/subagent_fork/wait_for/auto_session_title 四项漏探
- 优先级语义跟随上游 flagService：单 flag env > [experimental] 显式值
  > master env（仅强制开）> 默认。master env 不再锁定 UI；setExperimentalFlag
  增加 explicitFalse 路径，关闭默认开/master 强开的 flag 时写字面 false
- 权限设置新增 dangerous_command_guard 开关（默认开，写 [permission]
  蛇形键；env KIMI_CODE_DANGEROUS_COMMAND_GUARD 运行时覆盖 config）
- 新增 11 个测试（注册表/写语义/守卫读写）

@@ -543,6 +543,12 @@ A: 需要分两步：
 **Q: 切换会覆盖其他供应商吗？**
 A: 不会。Kimi Code 的 `config.toml` 始终写入全部供应商，仅 `default_model` 决定生效项。这与 CLI 原生 `/provider` 行为一致。
 
+**Q: 在 Kimi Code CLI 里新增的顶层配置节（如 `[task]`/`[swarm]`）会被保存时删掉吗？**
+A: 不会（v0.7.10 起）。保存时以加载配置那一刻的顶层键为基线，CLI 后加的节原样保留；只有在本应用中显式删除的节才会从 `config.toml` 移除。
+
+**Q: 遇到 Kimi Code 新增的供应商类型（`type` 值）会怎样？**
+A: 原样保留，不再改写为 `kimi`。编辑界面会显示原始类型值（标注"未知类型"）；该供应商不支持的操作（如模型发现）会返回明确错误提示。

+- **修复：保存不再误删 CLI 新增的顶层配置节**。此前在 Kimi Switch 加载配置后，若 Kimi Code CLI 往 `config.toml` 写入了新的顶层节（如 0.38+ 的 `[task]` / `[swarm]` / `[cron]` / `[tools]` / `[identity]` / `[token_counting]` 等），回到 Kimi Switch 保存时会把这些节**静默删除**。现在以导入时的顶层键为基线：CLI 后加的节原样保留；在界面中显式删除的节仍会被移除；老数据（无基线，如 SQLite 快照恢复）不删任何键
+- **修复：未知供应商类型不再被改写**。`config.toml` 中 Kimi Code 新增的供应商 `type` 值往返读写后不再被改写成 `kimi`，原样保留；编辑器 API 格式下拉框显示原始值（标注"未知类型"）；模型发现等不支持的操作返回明确错误提示，不再误用 `KIMI_API_KEY`
+- SQLite 快照恢复路径同步修复（此前从快照恢复同样会丢失未知类型）
+- 新增 3 个配置往返回归测试（Rust 测试 106 项全绿，前端 tsc / vitest 通过）

+
+### 适配 kimi-code 0.39.1
+
+- **修复：`[thinking]` 保留开关不再破坏思考配置**。此前在 UI 关闭"保留思考内容"会写入布尔 `keep = false`，而上游两个引擎都只接受字符串——v2 会把整个 `[thinking]` 节校验失败并丢弃。现改为写 `keep = "off"`，存量配置里的布尔值加载时自动归一化
+- **修复：`loop_control` 不再触发上游废弃告警**。默认只写新键 `max_attempts_per_step` 并清理存量旧键 `max_retries_per_step`；仅检测到 `KIMI_CODE_LEGACY_FLAG`（v1 引擎）时才双写
+- **思考强度移除 `max` 档**（上游已自动迁移为 `high`），存量配置显示归一
+- **实验开关同步上游全集**：新增 remote-control；`wait_for` 与 persistence_minidb_readmodel 已在上游转正默认开启，UI 会标注"默认开启"（显式关闭优先）
+
+### 会话归档与上游 v2 对齐
+
+- **归档不再搬动文件**：改为在会话 `state.json` 写入 `archived`/`archivedAt` 元数据（与 CLI v2 的 `setArchived` 逐字段一致），CLI 侧与 Kimi Switch 侧归档状态从此互通
+- 旧版本物理归档的会话（`.kcd-archive/` 目录）仍可识别为已归档并正常恢复
+- 归档不再改写 `session_index.jsonl`（删除会话的行为不变）
+
+### 子代理模型池修复
+
+- **修复：模型池无法添加第二个条目**。从"仅默认模型"的隐式单条目形态添加条目时，默认模型现在会自动物化进池，不再被"默认模型不在模型池中"的校验拦截
+
+### 模型数据同步
+
+- models.dev 快照刷新至 **7482 个模型 / 207 个供应商**

+- **flag 优先级语义修正**：跟随上游新优先级——单 flag 环境变量 > `[experimental]` 显式配置 > 总开关环境变量（仅强制开）> 默认值。总开关 `KIMI_CODE_EXPERIMENTAL_FLAG` 不再锁定全部开关，显式写入的 false/true 优先生效
+- **环境变量探测补齐**：`tower` / `subagent_fork` / `wait_for` / `auto_session_title` 等此前漏探测的环境变量现在会正确显示"被环境变量锁定"状态
+- **新增危险命令守卫开关**：权限设置页可配置 `[permission] dangerous_command_guard`（默认开启）——Auto 模式直接拒绝 `rm -rf` / `shutdown` 等危险命令，其它模式强制询问，关闭后回归旧行为
+
+## 修复
