test(shared): useWorkbenchSessionChrome/TranscriptChrome/SettingsRoute 补 62 个单元测试（Lane D #1764 第十一批）

[DeliciousBuding]

Summary

延续 #1765–#1779，落地 Lane D 前端测试补债 (#1764) 第十一批：给最后 3 个 workbench hook 补 62 个单元测试。不改任何产品代码。至此 workbench route/chrome hook 层全量覆盖（agents/docs/contacts/projects/tasks/settings routes + session/transcript/profile chrome + panelLayout）。

为什么选它

• useWorkbenchSessionChrome.ts：会话 chrome 编排（会话解析、composer 派发、证据/摘要推导、CLI 发现、导入门控）。
• useWorkbenchTranscriptChrome.ts：transcript 交互（上下文菜单、多选条、热键、hold-to-select、权限决策）。
• useWorkbenchSettingsRoute.ts：设置持久化（mock/fake/真实 service 三场景）。

覆盖范围

• sessionChrome（+23）：默认空壳/会话解析/草稿保存/agent 映射/证据摘要/自动清空/CLI 发现/导入门控/搜索/主题切换/导出双分支
• transcriptChrome（+18）：上下文菜单组形状/多选/复制脉冲/regenerate/approve-deny/pin-unpin-react-recall REST/热键/hold-to-select/选区矩形
• settingsRoute（+21）：无 service 默认值、fake service 接线与 write-through、真实 createSettingsService 集成、dataMode 双持久化语义

Test plan

• vitest run 新文件 — 62/62 通过
• tsc --noEmit 全包 0 错误
• CI 前端测试 job 通过

• Lane D 测试补债：[P1] 前端测试补债：shared/workbench 核心 store/hook/util 单元测试 #1764（第十一批）
• real_tested=true：renderHook 真实逻辑；仅 mock SettingsPort 传输层

📝 Walkthrough

Walkthrough

Added comprehensive tests for three workbench hooks. The coverage includes session state and integrations, settings persistence and recovery, and transcript selection, actions, shortcuts, and pointer behavior.

Changes

Workbench hook tests

Layer / File(s)	Summary
Session state and projections app/shared/src/workbench/useWorkbenchSessionChrome.test.ts	Tests cover defaults, conversation switching, composer drafts, mentions, transcript projections, inspector state, and execution-target clearing.
Session integrations and callbacks app/shared/src/workbench/useWorkbenchSessionChrome.test.ts	Tests cover desktop discovery, runtime-session imports, search, settings initialization, theme changes, inspector callbacks, and evidence export.
Settings state and service integration app/shared/src/workbench/useWorkbenchSettingsRoute.test.ts	Tests cover local defaults, persistence, service initialization, subscriptions, setting writes, external updates, and cleanup.
Settings error recovery app/shared/src/workbench/useWorkbenchSettingsRoute.test.ts	Tests cover initialization retry, error dismissal, optimistic write failures, rollback, and recovery.
Transcript selection and menus app/shared/src/workbench/useWorkbenchTranscriptChrome.test.ts	Tests cover defaults, context menus, block and range selection, reset behavior, toasts, clipboard actions, and selection geometry.
Transcript actions and pointer interactions app/shared/src/workbench/useWorkbenchTranscriptChrome.test.ts	Tests cover regeneration, permissions, REST actions, forwarding, multi-select commands, keyboard shortcuts, and hold-to-select behavior.

Merge Risk: 🟡 Moderate · up to 8d4fe

This pull request only adds tests, but the settings suite can validate behavior that differs from the production service, and one transcript assertion may pass without exercising the intended permission branch; the frontend test check is also still pending. Merge should wait for these test-validity and readiness issues to be corrected or explicitly accepted.

In `@app/shared/src/workbench/useWorkbenchSessionChrome.test.ts`:
- Line 1: Change the file-level real_tested marker from true to false, since the
tests use a fake AgentHubPlatform and mocked host ports rather than real login,
model/API, or packaged Desktop flows.

Apply the same fix in
`@app/shared/src/workbench/useWorkbenchSettingsRoute.test.ts` at line 1: Same
marker correction required for the settings suite.

Apply the same fix in
`@app/shared/src/workbench/useWorkbenchTranscriptChrome.test.ts` at line 1: Same
marker correction required for the transcript suite.

In `@app/shared/src/workbench/useWorkbenchSettingsRoute.test.ts`:
- Around line 21-86: Replace createFakeSettingsService and its
FakeSettingsService contract with createSettingsService configured through a
controlled mocked SettingsPort. Restrict the mock to port read and write
operations, and update the affected tests to use the real service behavior for
init, loading, and error state transitions while preserving listener assertions.

In `@app/shared/src/workbench/useWorkbenchTranscriptChrome.test.ts`:
- Around line 109-118: The test helper findMenuAction and its callers should
select menu actions by stable, typed action IDs rather than translated label
strings. Reuse the production action identifiers or expose them through the menu
model, and update the affected assertions to verify callback and state outcomes
without duplicating translation keys, menu matrices, or selection logic.
- Around line 193-211: Update the transcript fixture in the test “builds context
menu groups shaped for agent and user blocks” to include permissionBlock()
alongside the existing textBlock() and userTextBlock() entries, so
contextMenuGroups('perm-1') exercises the non-text block path before asserting
that the quote action is absent.
