* feat(ui): initialize shadcn/ui with button, dialog, input, select, tooltip, sonner
Set up shadcn/ui (v4) for Tailwind CSS v4 with CSS-first config. Added
path aliases (@/) to tsconfig.json and vite.config.ts. Installed six
components (button, dialog, input, select, tooltip, sonner) and wired
Sonner's <Toaster> into App.tsx for toast notifications. Removed the
next-themes dependency since this is a Vite/React project, not Next.js.

* fix(ui): resolve shadcn/ui CSS token conflicts with design system
- Namespace shadcn @theme inline variables (--color-cn-*) to avoid
overriding project's --color-border, --color-accent, --radius-* tokens
- Remove @apply border-border, bg-background, text-foreground, font-sans
that conflicted with our explicit CSS custom properties
- Remove dead Geist font import (we use system-ui)
- Remove ---break--- comment artifacts from shadcn CLI
