Initial commit: eldov.win portfolio with admin backend

Privates Portfolio von eldov (Jan Wagner). Next.js 16 / React 19 / Tailwind 4 /
SQLite. Eigenes Dark-/Terminal-Theme (Magenta+Grün-Akzente, ASCII-Boxen).

Public Routes (DE default, /en für Englisch):
- /, /ueber-mich, /projekte, /projekte/[slug], /kontakt, /impressum, /datenschutz
- Sitemap, robots, OG, JSON-LD

Admin (HMAC-Single-User, HttpOnly-Cookie):
- /admin/login, /admin/dashboard, /admin/profile, /admin/projects (CRUD)
- API: /api/admin/{login,logout,session,profile,projects,projects/[slug]}

Initial-Seed: Hermes, Casino-Bot, Polymarket-Trader, QuantMuse, Crypto-/Trade-Bot,
TS6-Bot, Freewarez-Landingpage, Minecraft-Portal, OSS-Themes, AI-Subscription-Manager,
LAMP-Link-Themes, Android. KEIN Batchmaker/W-Make (das gehört zu w-make.com).

Stack:
- better-sqlite3 mit Schema-Migration + idempotentem Seed
- HMAC-signiertes Session-Cookie mit timingSafeEqual
- Rate-Limit für /api/admin/login
- Docker + deploy-vps.sh analog w-make-com → free-warez.top
