refactor: flatten monorepo to single web package (#12)

Flatten the pnpm monorepo (apps/web + packages/*) into a single web package at the repo root. - Move app/lib/components/scripts/public to root; drop apps/web and packages/* wrappers - Rewrite tsconfig paths (@infiplot/*) to ./lib/*; turbopack.root = __dirname - Update Vercel (no root-directory) and Cloudflare (pnpm build:cf at root) deploy paths - Regenerate pnpm-lock.yaml to drop stale workspace importers - Bump engines.node to >=22 to match wrangler Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

+// later reuse).
+//
