`search.json` not generated when all website pages use `format: dashboard`

[mschnetzer]

Quarto's website search index (search.json) is never generated when every page in a type: website project uses format: dashboard, even with website.search: true explicitly set. Adding at least one non-dashboard page causes search.json to appear again, but it still only indexes the non-dashboard pages — dashboard pages themselves are never included.

Reproduction

_quarto.yml:

project:
  type: website

website:
  title: "Test"
  search: true

index.qmd:

---
title: home
format: dashboard
---

## Row

​```{r}
1+1
​```

Run quarto render. Expected: _site/search.json exists and indexes index.qmd. Actual: no search.json is created at all.

Adding a second dashboard page (format: dashboard) does not change this. Only adding a non-dashboard .qmd page causes search.json to reappear — but only that page's content is indexed, not the dashboards.

Environment: Quarto 1.9.38, macOS.

Any help appreciated, thank you!

Note that a dashboard is not a website page by definition.
