Lucide React integrations

These fixtures exercise the built lucide-react package in real consumer frameworks.

Every fixture runs three checks:

• a framework production build;
• TypeScript with noEmit;
• Vitest Browser Mode in Chromium.

From the repository root, install Chromium once and run the complete suite:

pnpm --filter @lucide/integration-react-vite exec playwright install chromium
pnpm test:integrations:react

The fixtures depend on lucide-react through workspace:*, but import only its public package entry points. The root command builds lucide-react before running any consumer checks.
