Hash-based config links like /config/#reporters relied on a client-side
router hook to redirect to /config/reporters. This broke when opening
links in a new tab (Ctrl+Click) since the hook only runs on client-side
navigation, not on fresh page loads — causing hydration mismatches or
wrong content (vitest-dev#9593).

Applied via one-shot script (node fix-config-links.mjs from repo root):

```js
