- Promote integrations from ?view=integrations to real /integrations and nested /integrations/[card] routes; the page body is shared via AppExperience and useViewMode is path-aware.
- Legacy ?view= URLs (and /settings/integrations) redirect to the new routes for back-compat; middleware/ensure-workspace allow the public routes.
- Add ?connect=<plugin|provider> deeplink that opens a card's connect modal instantly with a loading state (e.g. Hermes API key).
