feat: rebrand to Domain Scanner platform

Replace GeoExport static site with Next.js domain intelligence app:
real DNS/WHOIS/SSL/HTTP/geo scans, SSE progress, Docker stack,
updated install/uninstall scripts, and full documentation.

+# Architecture
+
+## Overview
+
+Domain Scanner is a Next.js 15 application with PostgreSQL (Prisma) and optional Redis caching. Scans run in-process on the web server using Node.js built-ins and public APIs.
+
+## Components
+
+```
+┌─────────────┐     ┌──────────────┐     ┌─────────────┐
+│   Browser   │────▶│  Next.js App │────▶│ PostgreSQL  │
+│  (SSE/REST) │     │  scan worker │     │   scans     │
+└─────────────┘     └──────┬───────┘     └─────────────┘
+                           │
+                    ┌──────▼───────┐
+                    │    Redis     │
+                    │ scan cache   │
+                    └──────────────┘
+```
+
+## Scan pipeline
+
+1. `POST /api/scan` validates domain, checks rate limit, creates `Scan` row
+2. Async `runDomainScan()` updates progress in DB
+3. Client subscribes to `GET /api/scan/:id/stream` (SSE)
+4. Completed results cached in Redis (1h) and stored as JSON in Postgres
+
+## Data model
+
+- **User** — credentials auth (NextAuth)
+- **Scan** — domain, status, progress, result JSON
+- **Monitor** — per-user DNS/SSL/uptime watch (cron stub)
+- **ApiRateLimit** — hourly per-IP counters
+
+## Competitive positioning
+
+Tools like DNSChecker and SecurityTrails focus on single-record lookups or enterprise datasets. Domain Scanner targets unified infrastructure snapshots with export and self-hosting — not a clone of their UI patterns.
+
+## Roadmap
+
+- BullMQ worker container for monitors
+- GraphQL server (schema placeholder in `src/lib/graphql/schema.ts`)
+- Blacklist checks (Spamhaus, etc.)
+- DNS diff history

+# Deployment
+
+## Docker (recommended)
+
+```bash
+docker compose up -d --build
+docker compose exec web npx prisma db push
+```
+
+## VPS one-liner
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/andrey271192/Domain_web/main/install.sh | sudo bash
+```
+
+Install path: `/opt/domain_web`  
+Service: Docker Compose (`web`, `postgres`, `redis`)  
+Nginx site: `domain-scanner` on port 80 → app `:3000`
+
+## Environment on server
+
+Edit `/opt/domain_web/.env`:
+
+- `NEXTAUTH_SECRET` — auto-generated on first install
+- `NEXTAUTH_URL` / `NEXT_PUBLIC_APP_URL` — public IP or domain
+
+## Manual Node deploy
+
+```bash
+npm ci && npm run build
+DATABASE_URL=... npx prisma db push
+PORT=3000 npm start
+```
+
+## SSL / HTTPS
+
+Place certbot in front of nginx or terminate TLS at a reverse proxy.
+
+## Upgrades
+
+```bash
+cd /opt/domain_web && git pull && docker compose up -d --build
+```
