🔴 High · Update the website consumer for the renamed guides contract

This renames the sidebar section and content directory from learn to guides, but the website still reads actors.learn in src/sitemap/products.ts and only routes content IDs under actors/learn in src/pages/guides/[...slug].astro. Consequently the migrated cookbook pages (including /guides/ai-agent) disappear from both static paths and navigation, while the four newly vendored guides are ignored in favor of stale duplicate files under src/content/guides. Update the routing/sidebar contract to consume actors.guides and actors/guides/* (and remove the duplicate website-owned entries), or preserve the old bundle shape until those consumers are migrated.
