Hub page fails axe: unnamed dock iframe and no landmarks #206

The standalone hub page (/__devframes/) has two axe violations, in both light and dark:

• frame-title: the dock iframe has no accessible name.
• landmark-one-main / region: the page content is not inside any landmark.

Both come from @devframes/hub-ui, not from our panel. The fix is upstream in devframes/devframe#425: each dock iframe gets its localized dock title, and the dock list and content area become nav and main landmarks. Checked with axe on the hub-ui playground: both violations are gone with the change.

To close this: once devframe#425 is released, bump @devframes/* here and re-run axe on /__devframes/.
