fix: add missing radix-ui umbrella package dependency

All shadcn/ui components in src/components/ui/ were already written against
the new shadcn convention of importing from the "radix-ui" umbrella package
(e.g. `import { Tooltip as TooltipPrimitive } from "radix-ui"`), but
"radix-ui" was never declared in package.json — only the individual
@radix-ui/* packages were listed.

This caused `npm i` + `vite build` to fail outside Shakespeare with:
  [plugin:vite:import-analysis] Failed to resolve import "radix-ui"

Fix: add `"radix-ui": "^1.0.1"` to dependencies (resolved to 1.5.0 in
the lock file). No code changes needed.
