GLIDELO / VERCEL OTHER PRESET FIX

This archive is intentionally configured for Vercel Framework Preset: Other.
It no longer contains the Next.js framework dependency, next.config.ts, or App Router entry files.

Expected Vercel settings:
- Framework Preset: Other
- Install Command: pnpm install --frozen-lockfile
- Build Command: pnpm build
- Output Directory: dist-vercel
- Root Directory: repository root / folder containing package.json

vercel.json carries the same settings and an explicit root rewrite to /index.html.
