Add footer with popular package catalog links

[Copilot]

Adds a footer to all pages with quick access to popular package catalogs and site navigation.

Changes

• Popular Packages Section: 7 clickable links to catalog pages (react, next, vue, typescript, express, lodash, axios)
• Site Navigation: Links to About, API, Source Trust pages and GitHub repository
• Copyright: Static year (2026) to avoid prerendering issues with Date in server components
• Layout: Responsive design that stacks on mobile, horizontal on desktop

Implementation

Updated src/app/_layout/Footer.tsx from empty wrapper to fully rendered footer. Uses server component pattern - no client JS needed.

Catalog Page

Original prompt

Now that we have a "catalog" feature, I want to add a footer which mainly should contain links to the catalog page of 6-7 most popular packages, like at least react, maybe next, and something more. I don't know what else we should have in the footer, but make it make sense.
