fix: resolve Next.js build failure by removing Vue archive

- Removed vue-archive directory containing old Nuxt code
- Removed harborsmith-nextjs temporary directory
- Updated tsconfig.json to exclude archived directories
- Updated .dockerignore to exclude archived code
- Updated .gitignore with proper Next.js patterns
- Updated README.md to reflect current project structure

Build now completes successfully without TypeScript errors.
