feat(website): redesign landing page and registry around the virtual OS narrative

[NicholasKissel]

• Reframe the landing page around the virtual operating system positioning: new hero copy, benchmark chips with named baselines, and works-with rows covering agent harnesses plus Eve, Flue, and RivetKit
• Consolidate the sandbox argument into one section: comparison ledger with inline topology cells, a cold-start timeline modal behind the Startup row, benchmark charts defaulting to the same figures the hero claims, and honest limitation rows (Virtualization, Isolation, Heavy workloads)
• Add an execution layers section (JS, Python, shell) sharing the tabbed code panel, with a new Python snippet; remap the OS bento to persistence, integrations, previews, human-in-the-loop, and memory
• Retitle the registry marquee to tools-first curation and trim orchestration to six tabs and four tiles
• Add a closing CTA naming Apache 2.0 with a GitHub link; remove unused hero components
• Refresh the registry storefront and package detail pages
• Docs: align the quickstart adapter list and the versus-sandbox credentials row with the page
