feat: initial commit — World Cup stats app with pnpm, Traefik, Docker

Full-stack World Cup web app (1930–2026):
- Next.js 16 + TailwindCSS 4 + GraphQL Yoga + Apollo Client 4 + Drizzle + PostgreSQL 16
- 23 tournaments synced from openfootball/worldcup.json (matches, goals, teams, stadiums, squads, standings)
- Pages: home (live), groups, stats, history, search, /tournaments/[year], /teams/[slug], /players/[name]
- Live match detection via isLive() + Apollo 60 s poll
- pnpm with node-linker=hoisted for Docker compatibility
- docker-compose.yml with Traefik labels (HTTPS redirect, TLS, security middleware)
- docker-compose.dev.yml for local dev (DB only, port 5432 exposed)
- Dockerfile: multi-stage pnpm build, standalone Next.js output, sync script bundled
- .env.example with all required variables documented
- Comprehensive README with local dev, deployment, schema, and GraphQL API reference
