feat(website): link comparison guides in footer

[NicholasKissel]

• Add a "Compare" column to the marketing site footer
• Link the Rivet vs Cloudflare Durable Objects and Rivet vs Temporal comparison guides

Note: the /compare pages stay noindex and out of the sitemap; this only makes them reachable from the footer, it does not change their indexing.

Review

Small, self-contained change: adds a "Compare" footer column linking to the existing /compare/rivet-vs-cloudflare-durable-objects and /compare/rivet-vs-temporal pages.

Verified correct:

• Both hrefs resolve to real, existing slugs in website/src/data/compare/{cloudflare-durable-objects,temporal}.tsx.
• website/astro.config.mjs already excludes /compare from the sitemap, and [slug].astro sets robots="noindex, nofollow" — consistent with the PR description's claim that indexing is unaffected.
• lg:grid-cols-6 is the right column count: 1 brand column + 5 category columns (Product, Developers, Resources, Compare, Legal).
• Follows the existing column pattern exactly (heading classes, <ul>/<li> structure, link styling), so no new patterns introduced.

Minor (non-blocking) nit — worth a visual check:
The category count went from 4 to 5, but md:grid-cols-4 and min-[440px]:grid-cols-2 weren't adjusted. At those breakpoints the 5 category columns no longer divide evenly, so the last column ("Legal") will land alone on its own row instead of pairing up like before. Purely cosmetic, but worth a quick look at tablet (768–1023px) and small (440–767px) widths to confirm it still reads fine.

Other:

• No security, performance, or test-coverage concerns — this is static internal marketing content with no logic branches.
