AgentTimeline 代理时间线

单个 agent 的行动时间线：thought / tool / action / observation / message / error 节点，纵向流式展开，每节点带 timestamp + duration + meta。

基础用法

适合记录 / 回放一个 agent 的完整执行过程。事件按数组顺序渲染，每条都展示 type 徽章 + 标题 + 耗时 + 时间戳，可选 mono 字体的 content 和 meta key/value 表格。

背景视口

修复 dashboard P99 加载慢。先看 trace 找瓶颈。

{ service: "web-dashboard", lookback: "1h", min_duration: "1s" }

spans: 142
slowest: 4.2s

SELECT * FROM entries WHERE user_id = ? ORDER BY created_at DESC

EXPLAIN: Seq Scan on entries, rows=2.4M, cost=12834..98231

action创建迁移 add_idx_entries_user_created50 ms09:01:21

请 review；P99 预期从 4.2s → 80ms。
