optimize images and fix vercel function size limit

- compress 68 images, saving 239MB total
- resize images wider than 2000px to reduce file size
- configure next.js outputFileTracingExcludes to prevent public directory from being bundled into serverless functions
- add exclusions for all routes including tags, posts, and api routes

this fixes the "max serverless function size of 250 MB exceeded" error on vercel by ensuring static assets are served via cdn instead of being packaged into function bundles.
