fix(shared): AgentStreamingBar/CompactDivider/ChatViewTranscript 硬编码中文迁移到 i18n

[DeliciousBuding]

Summary

延续 #1747-#1753 i18n 战役，迁移聊天流中剩余的用户可见硬编码中文字符串：

• AgentStreamingBar: 5 个状态标签（调度中…/思考中…/输出中…/完成/失败）+ 工具调用计数 + 多 Agent 运行中标签 → agentStreaming.* 键；statusLabel 函数重构为 STATUS_LABEL_KEY record + t() lookup（与现有 STATUS_ICON 模式一致）
• CompactDivider: "上下文已压缩" + "(自动)" + "tokens 前" → compactDivider.* 键（含 {{tokens}} 插值）
• ChatViewTranscript: 置顶公告 "由 X 置顶" / "系统" → pinnedAnnouncement.* 键（含 {{author}} 插值，处理中英词序差异）
• AgentStreamingBar.test.tsx: 加 useTestI18nLanguage('zh') + beforeAll 对齐 P2: 统一前端测试 i18next 实例与资源入口 #1717 测试 i18n 模式

Limit details: You’ve used all 1 included review currently available under your plan.

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

The PR replaces hardcoded Chinese ChatView text with localized Chinese and English translation keys. It updates compact dividers, pinned announcements, and agent streaming statuses, counts, and tool-call labels. Tests initialize the Chinese i18n language.

Changes

ChatView localization

Layer / File(s)	Summary
Translation resources and ChatView labels app/shared/src/chatview/i18n/resources.ts, app/shared/src/chatview/components/CompactDivider.tsx, app/shared/src/chatview/components/ChatViewTranscript.tsx	Added Chinese and English keys for compact dividers, agent streaming text, and pinned announcements. Components now use localized labels and fallback author text.
Agent streaming status localization app/shared/src/ui/AgentStreamingBar.tsx, app/shared/src/ui/AgentStreamingBar.test.tsx	Agent activity statuses, tool-call text, and agent counts now use ChatView translations. Tests initialize the Chinese test language.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 5f30e

This change moves visible chat-status, compaction, and pinned-announcement text into i18n without changing the core chat flow. Before merge, the required repository checks should be completed, and the English count wording, token-count phrasing, and test-language isolation should be corrected to avoid misleading UI text or order-dependent tests.

Inline comments:
In `@app/shared/src/chatview/i18n/resources.ts`:
- Around line 746-747: Update the English translations for
agentStreaming.toolCalls and agentStreaming.multiAgent to render grammatically
correct text when count is 1, using plural-aware entries or grammar-neutral
wording while preserving the count placeholder.
- Line 146: Rename the compact-divider translation key from
compactDivider.tokensAgo to compactDivider.tokensBefore, update its English and
Chinese wording to indicate the token count before compaction rather than
elapsed time, and update the corresponding lookup in CompactDivider.tsx to use
tokensBefore.

In `@app/shared/src/ui/AgentStreamingBar.test.tsx`:
- Around line 8-10: Update the AgentStreamingBar test suite’s i18n setup to
capture the language before useTestI18nLanguage('zh') changes the shared
instance, then restore that captured language in afterAll; keep the existing
activity-store cleanup intact.
- Around line 8-10: Update the AgentStreamingBar tests and their assertions
around the language-switch cases to avoid hardcoded Chinese production
translation literals; use semantic assertions or an isolated test translation
fixture with distinct values, while still verifying the component resolves the
expected translation keys.
