test(web): lifecycle & chrome scenarios — workspace flow, reload recovery, dark mode

One tiny recorded text turn drives three whole-page concerns: - workspace flow over the real wire: the empty-state hero's first send materializes a real Workspace + Session (the jsdom workspace-flow suite pins this state machine over the fixture client; this scenario pins it through HTTP RPC + SSE + the gateway). Durable proof: the session header's cwd is the create-by-name target <workspaceRoot>/workspace. Adds the hero waiting-state aria golden. - reload recovery: collapse the sidebar (persisted dsh.layout.panels), page.reload, and the surface comes back whole from persistence alone — layout collapsed, selection restored (dsh.sessions.current), the recorded turn re-rendered from session.history with zero model calls (the drained replay cursor makes any stray request fail loud at close). - dark mode: no product control flips the theme yet, so the scenario drives the ThemeService's entire DOM contract — body[data-ds-dark-theme] — and pins the shipped cascade: the alias token flips, a painted surface repaints, and removing the attribute restores the light sample exactly. TODO(web-theme-gesture) upgrades to a real settings control; no theme golden per the lane's scope ruling (aria is color-blind). Agent Note scenario list extended in both languages; pairing re-recorded.

 4. **`question-composer`** — the shipped composition's resident `ask_user_question` takeover: a recorded turn blocks mid-step on the real userInteraction seam, the composer (`[data-question-key]`) renders in the browser, the test answers through it (the ONE sanctioned place a drive step reacts to model content: the turn cannot complete without the answer, in record and replay alike), and the tool result carries the chosen label. Golden: the composer's stable waiting state.
 5. **`steering`** — mid-turn steer while the question composer blocks the step (the deterministic mid-turn window; no timing dependence). The composer locks while running, so the steer POSTs `session.prompt` `mode:'steer'` from the page over the same same-origin `/api` wire the client uses (`TODO(web-steer-composer)`: drive a composer gesture once one exists); everything downstream is product — gateway → `Agent.steer` → step-boundary drain → durable `steering/message` → SSE → badged interjection bubble. Record-mode fixture honesty: the recording is rejected unless the live model's final reply obeys an instruction only the steering message carries.
 6. **`navigation-panes`** — one rich two-turn seed (turn 1: bash + two parallel reads in one assistant message; turn 2: a markdown-heavy reply) rendered cold through the seeded-history pattern (zero model calls), serving four surfaces: sidebar search (client-side title filter — asserted only after the durable title lands with the attach baseline, because a cold `SessionSummary` carries no title and search matches the `displayTitle` the user sees; negative query empties the tree, positive narrows, clear restores), the Trajectory tab (turn sections + the step group's tool mix plus the view-area aria golden), the Waterfall tab (span stats + one lane per span — the P-I fold counts a turn-0 prologue span because only assistant/steering nodes carry a turn number, pinned as-is), and the details column (the bash toolview row routes click to openDetails; open/closed is asserted on the frame's `data-details-collapsed` attribute because close collapses the grid column to width 0 without unmounting the subtree).
+7. **`lifecycle-chrome`** — one tiny recorded text turn drives three whole-page concerns. Workspace flow over the real wire: the empty-state hero's first send materializes a real Workspace + Session (the jsdom `workspace-flow.snapshot.ts` suite pins this state machine over the fixture client; this scenario pins it through HTTP RPC + SSE + the gateway), proven durably by the session header's cwd being the create-by-name target `<workspaceRoot>/workspace`, plus the hero waiting-state aria golden. Reload recovery: collapse the sidebar (persisted `dsh.layout.panels`), `page.reload`, and the surface comes back whole from persistence alone — layout collapsed, selection restored (`dsh.sessions.current`), the recorded turn re-rendered from `session.history` with zero model calls (the drained replay cursor makes any stray request fail loud at close). Dark mode: no product control flips the theme yet, so the scenario drives the ThemeService's entire DOM contract — the `body[data-ds-dark-theme]` attribute — and pins the shipped cascade: the alias token flips, a painted surface repaints, and removing the attribute restores the light sample exactly (`TODO(web-theme-gesture)` upgrades to a real settings control); per the scope ruling there is no theme/layout golden (aria is color-blind).

 4. **`question-composer`**——已交付组合中常驻的 `ask_user_question` 接管：一段已录轮次在真实的 userInteraction seam 上阻塞于步骤中途，提问输入框（`[data-question-key]`）在浏览器中渲染，测试经它作答（这是驱动步骤对模型内容作出反应的唯一获准之处：没有这个回答，轮次无法完成，record 与 replay 皆然），工具结果携带所选的 label。预期输出：提问输入框稳定的等待态。
 5. **`steering`**——在提问输入框阻塞该步骤时做轮次中途 steering（中途引导），此即确定性的轮次中途窗口，不依赖任何时序。输入框在运行期间锁定，因此这一 steer 由页面经客户端所用的同一条同源 `/api` wire POST `session.prompt` `mode:'steer'`（`TODO(web-steer-composer)`：待有输入框手势后改为驱动它）；下游的一切都是产品路径——gateway → `Agent.steer` → 步骤边界排空 → 持久的 `steering/message` → SSE → 带徽标的插话气泡。record 模式的 fixture 诚实性：除非真实模型的最终回复遵循了一条只有 steering 消息才携带的指令，否则该次录制被拒绝。
 6. **`navigation-panes`**——一份内容丰富的双轮次种子（轮次 1：同一条 assistant 消息内的 bash + 两次并行 read；轮次 2：一段 markdown 密集的回复）经 seeded-history 模式冷渲染（零模型调用），承载四个表面：侧栏搜索（客户端标题过滤；仅在持久的标题随 attach 基线一同到达后才断言，因为冷的 `SessionSummary` 不携带标题，而搜索匹配的是用户所见的 `displayTitle`；反例查询清空整棵树，正例查询收窄，清除后复原）、Trajectory 标签页（轮次分节 + 步骤组的工具构成，外加视图区 aria 预期输出）、Waterfall 标签页（span 统计 + 每个 span 一条泳道；只有 assistant/steering 节点携带轮次编号，因此 P-I 折叠会将一个轮次 0 的序幕 span 计入，按原样钉住）与详情列（bash 工具视图行把点击路由到 openDetails；打开/关闭状态断言在 frame 的 `data-details-collapsed` 属性上，因为关闭把网格列收缩到宽度 0 而不卸载子树）。
+7. **`lifecycle-chrome`**——一段极小的已录纯文本轮次驱动三个整页关注点。真实 wire 上的 Workspace 动线：空态 hero 的首次发送物化出真实的 Workspace + Session（jsdom 的 `workspace-flow.snapshot.ts` 套件基于 fixture 客户端钉住这一状态机；本场景则经 HTTP RPC + SSE + gateway 钉住它），其持久证据是会话头部的 cwd 恰为按名创建的目标 `<workspaceRoot>/workspace`，外加 hero 等待态的 aria 预期输出。重新加载恢复：折叠侧栏（持久化于 `dsh.layout.panels`），`page.reload`，整个表面纯凭持久化完整归来——布局保持折叠，选中项恢复（`dsh.sessions.current`），已录轮次从 `session.history` 重新渲染且零模型调用（已耗尽的回放游标使任何离群请求都在 close 时大声失败）。暗色模式：产品尚无任何控件能切换主题，因此本场景驱动 ThemeService 的整个 DOM 契约（即 `body[data-ds-dark-theme]` 属性），并钉住已交付的级联：alias token 翻转，某个实际绘制的表面重绘，移除该属性则精确还原亮色采样值（`TODO(web-theme-gesture)`：待有真实设置控件后升级为驱动它）；按范围裁定，主题/布局不设预期输出（aria 感知不到颜色）。
