CRITICAL FIX: Completely remove middleware file to resolve deployment failures

- Deleted src/middleware.ts entirely instead of commenting it out
- Next.js was still compiling and invoking empty middleware causing MIDDLEWARE_INVOCATION_FAILED
- Middleware manifest now shows empty middleware object
- Only og-image edge function remains (which is working correctly)

Root cause: Next.js 15.3.4 compiles ANY middleware.ts file even if empty/commented
Solution: Complete file removal to eliminate middleware from build process
