Release version 0.19.1

feat(agents): Claude's built-in sub-agent activity now shows up live. Task runs, background shell watchers, and hooks that fire mid-reply appear as they happen, instead of only surfacing after you reopen the conversation.
fix(fork): Forking a conversation is reliable again. Forks no longer fail with a "database is locked" error, and forking a resumed conversation now branches from the right point instead of replaying duplicated history.
fix(sidebar): Delegation sub-sessions are ordered newest-first. The latest sub-agent appears at the top under its parent, matching the rest of the sidebar — no more scrolling to the bottom to find it.
fix(i18n): The live tool-use counter now appears in your language. The per-turn tool-activity count shown while a reply is streaming was previously left untranslated — it's now localized across all supported languages.
perf(workspace): The first code block in a reply renders without a stall. The syntax-highlighting engine now warms up off the streaming path, so it's ready before the first code block appears.
perf(workspace): Cosmetic conversation updates skip the stats recompute. Changes that only touch a conversation's status, title, or pin state no longer trigger a token/message-count recalculation.
chore(agents): Bundled agents updated — Claude Code 0.57.0(0.3.202), Gemini 0.49.0, OpenCode 1.17.14, CodeBuddy 2.117.1, Kimi Code 0.23.1, and Cline 3.0.38.

发布版本 0.19.1

功能(智能体)：Claude 内置子智能体的活动现在实时可见。 回复过程中触发的 Task 运行、后台 shell 监视器和 hook 会即时呈现，不再需要重新打开会话才能看到。
修复(分叉)：会话分叉重新变得可靠。 分叉不再因「database is locked」而失败；对已恢复的会话分叉时，也会从正确的位置开始，不再重放重复的历史记录。
修复(侧边栏)：委派子会话按最新在前排序。 最新的子智能体显示在父会话下方的顶部，与侧边栏其余部分保持一致——无需再滚动到底部去找。
修复(国际化)：实时工具调用计数现在会以你的语言显示。 回复流式过程中显示的本回合工具活动计数此前未翻译，现在已在所有支持的语言中完成本地化。
性能(工作区)：回复中的第一个代码块渲染不再卡顿。 语法高亮引擎会在流式路径之外提前预热，在第一个代码块出现前就已就绪。
性能(工作区)：仅涉及外观的会话更新会跳过统计重算。 仅改动会话的状态、标题或置顶状态时，不再触发 token / 消息数的重新计算。
更新(智能体)：内置智能体升级——Claude Code 0.57.0(0.3.202)、Gemini 0.49.0、OpenCode 1.17.14、CodeBuddy 2.117.1、Kimi Code 0.23.1、Cline 3.0.38。
