Release version 0.18.2

• feat(chat): Codex sub-agent collaboration now renders as clean, collapsible capsules — each sub-agent shows its task, live status, and result as markdown instead of raw spawn/wait/close tool calls, both live and when you reopen the session from history.
• feat(composer): A flowing gradient border marks the active session's composer in tiled multi-session workspaces, replacing the old top-center icon. It shows only while the input isn't focused; focusing it restores the standard focus ring.
• fix(office): Office Tools (officecli) now work in Docker and server deployments — the runtime images were missing the ICU library officecli needs, which had silently broken skill sync and document preview there. Such failures are now surfaced clearly instead of passing as success.
• chore(acp): Bundled agents updated — Codex on codex-acp 1.0.1 (codex 0.142.2), Cline 3.0.31, CodeBuddy 2.112.1, and Kimi Code 0.20.1.

发布版本 0.18.2

• 功能(聊天)：Codex 子智能体协作现在以简洁、可折叠的胶囊呈现——每个子智能体显示其任务、实时状态与 markdown 结果，不再是原始的 spawn/wait/close 工具调用；实时与历史重开均一致。
• 功能(输入框)：平铺多会话时，当前活动会话的输入框由流动渐变边框标示，取代原先居中顶部的图标。仅在输入框未聚焦时出现，聚焦后恢复标准聚焦环。
• 修复(Office)：Office 工具（officecli）现在可在 Docker 与服务器部署中正常运行——此前运行镜像缺少 officecli 所需的 ICU 库，曾导致技能同步与文档预览在该环境下静默失效；现在此类失败也会明确上报，而非误判为成功。
• 更新(ACP)：内置智能体升级——Codex 改用 codex-acp 1.0.1（codex 0.142.2）、Cline 3.0.31、CodeBuddy 2.112.1、Kimi Code 0.20.1。
