Version: 0.9.33.dev.260419

后端： 1. deliver 收口上下文重构——历史折叠到工作区，仅基于本轮 execute 窗口诚实收口 - newAgent/prompt/deliver.go：BuildDeliverMessages 改为向 buildDeliverWorkspace 透传 ConversationContext - newAgent/prompt/deliver_context.go：deliver 的 msg1 改为轻量提示，不再回灌完整历史；msg2 追加本轮 execute 窗口与结果态信息前端： 2. 品牌命名统一切换为 SmartMate - index.html：页面标题从 SmartFlow 改为 SmartMate - package.json：前端包名改为 smartmate-frontend - App.vue：布局类名从 smartflow-* 统一改为 smartmate-* - stores/auth.ts：access/refresh token 与 last username 的 localStorage key 全部切到 smartmate_* - utils/idempotency.ts：默认幂等键前缀从 smartflow 改为 smartmate - DashboardView.vue：首页默认问候名从 SmartFlow 用户改为 SmartMate 用户 3. 助手页体验重做——默认空会话、排程卡片懒加载、上下文统计刷新时机收口 - components/dashboard/AssistantPanel.vue：进入页面不再自动打开最后一次会话，改为展示居中欢迎空态 - components/dashboard/AssistantPanel.vue：schedule_completed 改为先展示占位卡片，点击后再拉取 schedule preview，避免预览未落库时并发 404 - components/dashboard/AssistantPanel.vue：tool done、schedule card、SSE block done、[DONE] 与整轮流结束后统一刷新 context stats - components/dashboard/AssistantPanel.vue：重构聊天区布局、空态欢迎内容、底部交互区与内外边距，整体视觉切到更轻的阅读式界面 - views/AssistantView.vue：移除外层白底卡片壳，交由 AssistantPanel 自己承接容器视觉 4. 排程微调保存链路补幂等保护，并修正请求头口径 - api/schedule_agent.ts：正式应用接口请求头从 Idempotency-Key 改为 X-Idempotency-Key - components/assistant/ScheduleFineTuneModal.vue：同一预览会话复用稳定幂等键，保存成功后再刷新新 key，避免重试或延迟导致重复落库 - components/assistant/ScheduleResultCard.vue：结果卡片样式、hover 与进场动效整体升级 5. 任务类选择器与侧边导航细节调整 - components/assistant/TaskClassPlanningPicker.vue：popover、骨架屏、列表项、选中态与按钮视觉整体重绘 - components/common/MainSidebar.vue：移除“任务”占位入口，侧栏只保留总览 / 日程 / 助手 6. 登录页与首页展示风格重做 - views/AuthView.vue：品牌文案切到 SmartMate，登录/注册从 tabs 改为自定义双态切换，重做背景、玻璃卡片、表单与动效 - views/DashboardView.vue：首页主区改为 auto + 1fr 布局，锁定顶部栏高度，避免缩放时形变仓库： 7. README 全量更新到当前版本能力边界 - README.md：重写项目定位、功能描述、业务闭环图、newAgent graph 流程、工具定义、前端衔接边界、页面展示、部署方案与监控说明
