Cache blog metadata and posts, simplify motion components, improve scroll handling and font usage

[jakemcquade]

Motivation

• Reduce redundant work at runtime and make blog processing Workers-safe by caching post metadata and compiled post content.
• Improve runtime performance and memory by reusing the Shiki highlighter and returning metadata synchronously where possible.
• Fix scroll button behavior to be more robust and performant and simplify motion animation usage to match the motion/react API.
• Consolidate font handling into CSS variable usage and tidy build config for predictable sourcemap behavior.

Description

• Introduced metadataCache and postCache in src/lib/blog.ts and added a singleton highlighterPromise so getPost caches compiled posts and reuses the Shiki engine, while getBlogPosts now returns synchronous metadata entries via getPostMetadata.
• Updated page components to align with the new API by removing unnecessary await calls (src/app/blog/page.tsx and src/app/blog/[slug]/page.tsx) and making Blog an async component where appropriate.
• Reworked BackUp (src/components/backup.tsx) to use addEventListener/removeEventListener for scroll with a passive listener and a safe early return if the button node is missing, including cleanup on unmount.
• Simplified motion components: removed AnimatePresence and adapted BlurFadeText and BlurFade to use motion directly, added useMemo for defaultVariants in BlurFade to avoid recreating variant objects, and removed unused imports.
• Adjusted global layout/font handling by using the Inter font variable class in the body and switching the root font-family in src/styles/globals.css to reference var(--font-sans) with fallbacks.
• Updated vite.config.ts to disable sourcemaps in build and ensure rsc() is included in the plugin list (formatting tidy-up).

Testing

• Ran TypeScript type-check with tsc --noEmit and it completed successfully.
• Performed a production build with vite build to validate the Vite configuration and bundling, which succeeded.
