`ChatgptReasoning` is a shadcn `Collapsible` whose trigger is a ghost `Button`. It stays open while the answer streams and folds shut when `complete` turns `true`. Children and `search` slide in when the panel opens. Without either, it renders the label as plain text.

| Prop | Default | Description |
| --- | --- | --- |
| `seconds` | | Shown as "Worked for Ns". |
| `complete` | `false` | Collapses the trace when the answer finishes. |
| `search` | | Rendered under the trace, usually a `ChatgptActivity`. |
| `open`, `onOpenChange` | | Collapsible state, if you want to control it. |
