refactor(tasks): 移植主 Agent 同款合并活动折叠（数据层）

把上一轮验证过的数据层搬到工作图基座上，图/树两种模式共用： - 新增 src/process-activity.ts：宿主 ui-chat 的 process group 算法移植（activity() 分类表逐条照抄、liveToolDetail 键优先级与 160 字截断、 counts 计数排序与并列规则、preparing 语义、按 user/reply 边界切范围）。按本轮设计裁剪掉逐阶段列表（阶段改由徽标 + 颜色表达）。新增一条偏差：最新范围为空（子代理刚回复完）时回退到上一个「做过事」的范围，否则已结算卡片的小条只会显示「已完成分析」。 - chatT：从宿主 chat 命名空间读 message.stepProcess.* 措辞（方法调用 + try/catch 兜底，key 未命中即回退），4 个回归用例钉住「不许解绑 bind」。 - subagents.live 载荷换新：SidebarChildLiveView { running?, text?, summary?, lastEventTime? }，报告树内每个子节点（含已结算）与拓扑根；删除 expand/stages 机制；childActivity → childLive（「不在 map 里 = 未运行」的读法随旧协议一起作废）。 - tasks-model 消费新形状；LiveLine 与节点详情浮窗改显示合并活动措辞。 - 删除 src/subagent-activity.ts 与 tests/subagent-activity.spec.ts。验证：typecheck / lint 通过；pnpm test 1252 passed / 9 skipped。 (cherry picked from commit 5e5284f214846b0c366048acbee459f3a7a79456)
