Add generateStaticParams and generateMetadata to fix Next.js build failure

[Copilot]

CI build was failing during page data collection phase with TypeError: Cannot read properties of undefined (reading 'map') in the fumadocs documentation site.

Changes

• Added generateStaticParams() - Next.js requires this for catch-all routes [[...slug]] to determine which pages to statically generate
• Added generateMetadata() - Required for metadata generation during build; includes error handling for missing pages
• Switched to static generation - Changed dynamicParams to false and removed dynamic = 'force-dynamic'
• Updated Next.js to 15.3.0 - Matches [email protected] peer dependency requirement (was 15.1.6)
• Added root meta.json - Defines navigation structure for docs at content/docs/meta.json

export function generateStaticParams() {
  return source.generateParams();
}

export async function generateMetadata(props: {
  params: Promise<{ slug?: string[] }>;
}): Promise<Metadata> {
  const params = await props.params;
  const page = source.getPage(params.slug);
  
  if (!page) return {};
  
  return {
    title: page.data.title || 'Documentation',
    description: page.data.description || undefined,
  };
}

Note

Build still fails at same point. Root cause appears to be fumadocs-mdx 14.x / fumadocs-core 15.x compatibility issue or missing async mode configuration. These changes are necessary prerequisites but may not be sufficient.
