chore: scaffold monorepo for EventSnap

- Rust/Axum backend skeleton with all crates, multi-stage Dockerfile
- SvelteKit + TypeScript frontend with Tailwind CSS v4, adapter-node, Dockerfile
- docker-compose.yml: db (postgres:16) → app → frontend → caddy with healthcheck and named volumes
- Caddyfile: TLS via Let's Encrypt, cache headers, API/media routing to backend
- .env.example: all environment variables documented with defaults
- README.md: project overview, features, stack, deploy guide, roadmap
- .gitignore: excludes secrets, build artifacts, node_modules, media uploads
