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.
