feat(mitmproxy): Add enhanced threat patterns and README

Add modern attack detection patterns:
- SSTI (Jinja2, Twig, FreeMarker, ERB, Thymeleaf)
- Prototype Pollution (__proto__, constructor[])
- GraphQL abuse (introspection, deep nesting)
- JWT attacks (alg:none bypass, exposed tokens)
- CVE-2024-21887 (Ivanti Connect Secure)
- CVE-2024-1709 (ScreenConnect auth bypass)
- CVE-2024-27198 (TeamCity auth bypass)

Add comprehensive README documenting:
- Threat detection patterns and categories
- CrowdSec integration and scenarios
- GeoIP database setup
- File paths and dependencies

+# SecuBox mitmproxy App
+
+LXC container with mitmproxy for HTTPS traffic inspection and threat detection.
+
+## Components
+
+| Component | Description |
+|-----------|-------------|
+| **LXC Container** | Debian-based container with mitmproxy |
+| **secubox_analytics.py** | Threat detection addon for mitmproxy |
+| **haproxy_router.py** | HAProxy backend routing addon |
+| **CrowdSec Integration** | Threat logging for automatic IP banning |
+
+## Threat Detection Patterns
+
+### Attack Types Detected
+
+| Category | Patterns |
+|----------|----------|
+| **SQL Injection** | UNION SELECT, OR 1=1, SLEEP(), BENCHMARK() |
+| **XSS** | `<script>`, event handlers, javascript: URLs |
+| **Command Injection** | ; cat, \| ls, backticks, $() |
+| **Path Traversal** | ../, %2e%2e/, file:// |
+| **SSRF** | Internal IPs, metadata endpoints |
+| **XXE** | <!ENTITY, SYSTEM, file:// |
+| **LDAP Injection** | )(|, )(&, objectclass=* |
+| **Log4Shell** | ${jndi:, ${env:, ldap:// |
+| **SSTI** | {{...}}, ${...}, <%...%> |
+| **Prototype Pollution** | __proto__, constructor[ |
+| **GraphQL Abuse** | Deep nesting, introspection |
+| **JWT Attacks** | alg:none, exposed tokens |
+
+### CVE Detection
+
+| CVE | Description |
+|-----|-------------|
+| CVE-2021-44228 | Log4Shell (Log4j RCE) |
+| CVE-2021-41773 | Apache path traversal |
+| CVE-2022-22965 | Spring4Shell |
+| CVE-2023-34362 | MOVEit SQL injection |
+| CVE-2024-3400 | PAN-OS command injection |
+| CVE-2024-21887 | Ivanti Connect Secure |
+| CVE-2024-1709 | ScreenConnect auth bypass |
+| CVE-2024-27198 | TeamCity auth bypass |
+
+### Scanner Detection
+
+Detects security scanners: sqlmap, nikto, nuclei, burpsuite, nmap, dirb, gobuster, ffuf, etc.
+
+## CrowdSec Integration
+
+Threats are logged to `/data/threats.log` (mounted as `/srv/mitmproxy/threats.log` on host).
+
+CrowdSec scenarios:
+- `secubox/mitmproxy-attack` - Bans after 3 high/critical attacks
+- `secubox/mitmproxy-scanner` - Bans aggressive scanners
+- `secubox/mitmproxy-ssrf` - Bans external SSRF attempts
+- `secubox/mitmproxy-cve` - Immediate ban for CVE exploits
+
+## GeoIP
+
+Install GeoLite2-Country.mmdb to `/srv/mitmproxy/` for country detection:
+```bash
+curl -sL "https://github.com/P3TERX/GeoLite.mmdb/raw/download/GeoLite2-Country.mmdb" \
+  -o /srv/mitmproxy/GeoLite2-Country.mmdb
+```
+
+## File Paths
+
+| Path | Description |
+|------|-------------|
+| `/srv/mitmproxy/` | Host bind mount directory |
+| `/srv/mitmproxy/threats.log` | CrowdSec threat log |
+| `/srv/mitmproxy/addons/` | mitmproxy addon scripts |
+| `/srv/mitmproxy/GeoLite2-Country.mmdb` | GeoIP database |
+
+## Dependencies
+
+- `lxc` - Container runtime
+- `crowdsec` - Threat intelligence (optional)
+- `geoip2` - Python GeoIP library (optional)
