test(snapshots): refresh the web-fetch tool-schema pin for the parallel todo description

The web-fetch pinsHeader scenario landed on master after this branch, so its
tool-schemas.expected.json carried the old at-most-one-in_progress description
while replay assembles the new one. Refreshed keylessly with
DSH_SNAPSHOT=refresh; the Agent Note now records that every pinning scenario
carries its own copy of the description, so a branch changing it has to refresh
the pins that landed after it branched.

 ## Consequences
 
-A todo list can now faithfully mirror parallel execution, and every UI renders several active markers at once: the TUI's per-status prefix needed no change, the plan strip's header counts the active items, and the row needed the derivation above. The tool no longer rejects a formerly-invalid snapshot shape, so the change is compatible with every previously valid call; only the error path was removed. The model-facing description changed, which re-recorded the tool-catalog page and the assembled snapshot transcripts that pin the schema. The web fixture's todo sample now runs two items `in_progress`, so the assembled web transcript replays a parallel plan and would fail again if either surface returned to single-active derivation.

 ## 后果
 
-现在 todo 列表可以忠实反映并行执行，并且每个 UI 都能一次渲染多个活跃标记：TUI 按状态区分的前缀无需改动，计划横条的表头会计数活跃条目，工具行则需要上述推导。工具不再拒绝一种此前无效的快照形状，因此该改动兼容此前所有合法的调用；被移除的只是错误路径。面向模型的描述发生了变化，这重新记录了 tool-catalog 页面以及固定 schema 的组装后快照 transcript（文本记录）。web fixture 的 todo 样本现在有两个条目处于 `in_progress`，因此组装后的 web transcript 回放的是一个并行计划；若任一展示面退回单活跃项推导，它会再次失败。
