/**
 * Creates a middleware for Vite dev server to serve static assets like fonts and icons.

 * bypassing the need to copy them to the output directory during development.
 * @param server - The Vite development server instance.
 * @param mercuryOptions - Configuration options for Mercury.
 * @param metadataReusedBetweenHooks - Metadata reused between plugin hooks to optimize performance.
 * @returns A promise that resolves when the middleware is set up.
