fix: resolve Turbopack build issues in CI environment

Problem:
- Turbopack file tracing caused by process.cwd() in upload.ts
- Google fonts download failures in CI network environment
- Module resolution errors for @vercel/turbopack-next

Solutions:
- Add turbopackIgnore comment to process.cwd() call
- Temporarily disable Google fonts to avoid network dependencies
- Use system fonts as fallback for CI builds
- Switch to node:20-alpine for faster SSH installation
- Add SSH debugging information

This should resolve the 493 build errors and enable successful CI deployment.
