* chore(benchmarks): remove Vite 7 runner, update Next.js to 16.2.1 The vinext-rolldown benchmark runner was identical to the vinext runner (both resolved to the same Vite version via catalog), producing duplicate results on the dashboard. Remove it entirely and simplify to a two-runner comparison: Next.js (Turbopack) vs vinext (Vite 8). Also bump the Next.js benchmark dependency from 16.1.7 to 16.2.1 to pick up recent performance improvements. * fix: remove vinext-rolldown from pnpm-workspace.yaml, fix migration comment
