Add design-sync inputs for claude.ai/design

Import this repo's components into a Claude Design project so the design
agent builds with the real Cloudrite library instead of generic components.

The repo is a Next.js app, not a component library: no dist/, no exports
map, no .d.ts tree, and Tailwind exists only as build directives. So
.design-sync/ carries a small build that manufactures a consumable package
from source (staged to the gitignored .ds-pkg/):

- tsconfig.dts.json  declaration emit, for real <Name>Props contracts
- build-css.mjs      Tailwind v4 -> a static stylesheet via @tailwindcss/postcss
- make-pkg.mjs       stages the package; index.js exports all 292 symbols
                     while index.d.ts exports only the 61 roots, so shadcn's
                     flat compound parts don't each become a preview card.
                     Also generates the per-root parts tables in docs/
- shims/next-link    router-free anchor; the real next/link needs
                     AppRouterContext and drags in the App Router runtime
- fonts/             Space Grotesk + Inter woff2 (SIL OFL). next/font supplies
                     these at runtime in the app, so the bundle has none

previews/ holds 40 authored preview stories, conventions.md is prepended to
the generated README as the design agent's usage guide, and NOTES.md records
the gotchas a future sync would otherwise rediscover.

+# Sidebar
+
+Source: `components/ui/sidebar.tsx`.
+
+`Sidebar` is a compound component. Its parts are exported **flat** (`SidebarContent`, not
+`Sidebar.Content`) and each is a separate top-level export of the bundle:
+
+| Part | Props |
+| --- | --- |
+| `SidebarContent` | `React.ComponentProps<'div'>` |
+| `SidebarFooter` | `React.ComponentProps<'div'>` |
+| `SidebarGroup` | `React.ComponentProps<'div'>` |
+| `SidebarGroupAction` | `React.ComponentProps<'button'> & {…}` |
+| `SidebarGroupContent` | `React.ComponentProps<'div'>` |
+| `SidebarGroupLabel` | `React.ComponentProps<'div'> & {…}` |
+| `SidebarHeader` | `React.ComponentProps<'div'>` |
+| `SidebarInput` | `React.ComponentProps<typeof Input>` |
+| `SidebarInset` | `React.ComponentProps<'main'>` |
+| `SidebarMenu` | `React.ComponentProps<'ul'>` |
+| `SidebarMenuAction` | `React.ComponentProps<'button'> & {…}` |
+| `SidebarMenuBadge` | `React.ComponentProps<'div'>` |
+| `SidebarMenuButton` | `React.ComponentProps<'button'> & {…} & VariantProps<typeof sidebarMenuButtonVariants>` |
+| `SidebarMenuItem` | `React.ComponentProps<'li'>` |
+| `SidebarMenuSkeleton` | `React.ComponentProps<'div'> & {…}` |
+| `SidebarMenuSub` | `React.ComponentProps<'ul'>` |
+| `SidebarMenuSubButton` | `React.ComponentProps<'a'> & {…}` |
+| `SidebarMenuSubItem` | `React.ComponentProps<'li'>` |
+| `SidebarProvider` | `React.ComponentProps<'div'> & {…}` |
+| `SidebarRail` | `React.ComponentProps<'button'>` |
+| `SidebarSeparator` | `React.ComponentProps<typeof Separator>` |
+| `SidebarTrigger` | `React.ComponentProps<typeof Button>` |
+
+All parts accept `className` and are composed as children of `Sidebar`.
