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.

+# Command
+
+Source: `components/ui/command.tsx`.
+
+`Command` is a compound component. Its parts are exported **flat** (`CommandDialog`, not
+`Command.Dialog`) and each is a separate top-level export of the bundle:
+
+| Part | Props |
+| --- | --- |
+| `CommandDialog` | `React.ComponentProps<typeof Dialog> & {…}` |
+| `CommandInput` | `React.ComponentProps<typeof CommandPrimitive.Input>` |
+| `CommandList` | `React.ComponentProps<typeof CommandPrimitive.List>` |
+| `CommandEmpty` | `React.ComponentProps<typeof CommandPrimitive.Empty>` |
+| `CommandGroup` | `React.ComponentProps<typeof CommandPrimitive.Group>` |
+| `CommandItem` | `React.ComponentProps<typeof CommandPrimitive.Item>` |
+| `CommandShortcut` | `React.ComponentProps<'span'>` |
+| `CommandSeparator` | `React.ComponentProps<typeof CommandPrimitive.Separator>` |
+
+All parts accept `className` and are composed as children of `Command`.
