- Rebuild the integrations catalog as horizontally-scrollable category rails
(MCP, Plugins, Knowledge bases, Apps & extensions) with header chevrons
- Add an auto-rotating Featured hero with problem-led headlines, backdrop
imagery and a gradient FEATURED badge
- Surface all 9 MCP clients as individual cards that open a setup modal
styled like the plugin connect flow (reuses MCPSteps embedded variant)
- Align MCP setup steps and the Claude Desktop timeline to the design system
- Merge the Integrations and Connections settings tabs into one entry
- Fix `authClient.apiKey.create()` returning undefined: better-auth resolves to `{ data, error }`, not the key directly. Use `res.data.key` (with `res.error` handling) in both `RaycastDetail` and `settings/integrations.tsx`.
- Extract `RaycastSetupModal` and reuse it across the nova home Raycast card and the Settings → Integrations Raycast modal. The new modal matches the plugins-connect design system (icon box, pill close, inset card with shared `InstallSteps`, install pill).
- Add `/settings/integrations` redirect page so `app.supermemory.ai/settings/integrations?q=raycast` lands on the Integrations tab and auto-opens the Raycast modal (the `?q=raycast` auto-trigger logic already existed; the route was the missing piece).
