feat(iot-guard): Add IoT device isolation and security monitoring

Backend (secubox-iot-guard): - OUI-based device classification with 100+ IoT vendor prefixes - 10 device classes: camera, thermostat, lighting, plug, assistant, etc. - Risk scoring (0-100) with auto-isolation threshold - Anomaly detection: bandwidth spikes, port scans, time anomalies - Integration with Client Guardian, MAC Guardian, Vortex Firewall - iot-guardctl CLI for status/list/scan/isolate/trust/block - SQLite database for devices, anomalies, cloud dependencies - Traffic baseline profiles for common device classes Frontend (luci-app-iot-guard): - KISS-style overview dashboard with security score - Device management with isolate/trust/block actions - Vendor classification rules editor - Settings form for UCI configuration - RPCD handler with 11 methods - Public ACL for unauthenticated dashboard access Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

+58. **IoT Guard Implementation (2026-02-11)**
+    - Created `secubox-iot-guard` package — IoT device isolation, classification, and security monitoring.
+    - **Device Classification**:
+      - OUI-based classification with 100+ IoT manufacturer prefixes
+      - 10 device classes: camera, thermostat, lighting, plug, assistant, media, lock, sensor, diy, mixed
+      - Traffic-based classification from cloud dependency tracking
+      - Hostname-based classification fallback
+    - **Risk Scoring**:
+      - 0-100 risk score with vendor risk, anomaly penalty, cloud dependency penalty
+      - Risk levels: low (20), medium (50), high (80)
+      - Auto-isolation threshold configurable (default 80)
+    - **Anomaly Detection**:
+      - Bandwidth spike detection (Nx above baseline)
+      - New destination tracking
+      - Port scan behavior detection
+      - Time-based anomaly (unusual activity hours)
+    - **Integration Points**:
+      - Client Guardian: Zone assignment (IoT zone)
+      - MAC Guardian: L2 blocking/trust
+      - Vortex Firewall: DNS filtering for IoT malware feeds
+      - Bandwidth Manager: Rate limiting
+    - **CLI** (`iot-guardctl`): status, list, show, scan, isolate, trust, block, anomalies, cloud-map, daemon
+    - **UCI Configuration**: main settings, zone policy, vendor rules, allowlist, blocklist
+    - **Baseline Profiles**: JSON profiles for camera, thermostat, plug, assistant device classes
+    - Created `luci-app-iot-guard` — LuCI dashboard with KISS-style views.
+    - **Dashboard Views**:
+      - Overview: Security score, device counts, risk distribution, anomaly timeline
+      - Devices: Filterable table with device details, isolate/trust/block actions
+      - Policies: Vendor classification rules management
+      - Settings: UCI form for configuration
+    - **RPCD Handler**: 11 methods (status, get_devices, get_device, get_anomalies, scan, isolate/trust/block_device, get_vendor_rules, add/delete_vendor_rule, get_cloud_map)
+    - **ACL**: Public access for status and device list via `unauthenticated` group

+# SecuBox IoT Guard
+
+IoT device isolation, classification, and security monitoring for OpenWrt.
+
+## Overview
+
+IoT Guard provides automated IoT device management:
+
+- **Auto-Classification** - Identifies IoT devices by vendor OUI and behavior
+- **Risk Scoring** - Calculates security risk per device (0-100 scale)
+- **Auto-Isolation** - Automatically quarantines high-risk devices
+- **Anomaly Detection** - Monitors traffic patterns for behavioral anomalies
+- **Cloud Mapping** - Tracks cloud services each device contacts
+
+IoT Guard **orchestrates existing SecuBox modules** rather than reimplementing:
+
+| Module | Integration |
+|--------|-------------|
+| Client Guardian | Zone assignment (IoT zone) |
+| MAC Guardian | L2 blocking/trust |
+| Vortex Firewall | DNS filtering (IoT malware feeds) |
+| Bandwidth Manager | Rate limiting |
+
+## Installation
+
+```bash
+opkg install secubox-iot-guard luci-app-iot-guard
+```
+
+## CLI Usage
+
+```bash
+# Overview status
+iot-guardctl status
+
+# Scan network for IoT devices
+iot-guardctl scan
+
+# List all devices
+iot-guardctl list
+iot-guardctl list --json
+
+# Device details
+iot-guardctl show AA:BB:CC:DD:EE:FF
+
+# Isolate to IoT zone
+iot-guardctl isolate AA:BB:CC:DD:EE:FF
+
+# Trust device (add to allowlist)
+iot-guardctl trust AA:BB:CC:DD:EE:FF
+
+# Block device
+iot-guardctl block AA:BB:CC:DD:EE:FF
+
+# View anomalies
+iot-guardctl anomalies
+
+# Cloud dependency map
+iot-guardctl cloud-map AA:BB:CC:DD:EE:FF
+```
+
+## Configuration
+
+Edit `/etc/config/iot-guard`:
+
+```
+config iot-guard 'main'
+    option enabled '1'
+    option scan_interval '300'        # Network scan interval (seconds)
+    option auto_isolate '1'           # Auto-isolate high-risk devices
+    option auto_isolate_threshold '80' # Risk score threshold for auto-isolation
+    option anomaly_detection '1'      # Enable anomaly detection
+    option anomaly_sensitivity 'medium' # low/medium/high
+
+config zone_policy 'isolation'
+    option target_zone 'iot'          # Target zone for isolated devices
+    option block_lan '1'              # Block LAN access
+    option allow_internet '1'         # Allow internet access
+    option bandwidth_limit '10'       # Rate limit (Mbps)
+
+config vendor_rule 'ring'
+    option vendor_pattern 'Ring|Amazon Ring'
+    option oui_prefix '40:B4:CD'
+    option device_class 'camera'
+    option risk_level 'medium'
+    option auto_isolate '1'
+
+config allowlist 'trusted'
+    list mac 'AA:BB:CC:DD:EE:FF'
+
+config blocklist 'banned'
+    list mac 'AA:BB:CC:DD:EE:FF'
+```
+
+## Device Classes
+
+| Class | Description | Default Risk |
+|-------|-------------|--------------|
+| camera | IP cameras, video doorbells | medium |
+| thermostat | Smart thermostats, HVAC | low |
+| lighting | Smart bulbs, LED strips | low |
+| plug | Smart plugs, outlets | medium |
+| assistant | Voice assistants | medium |
+| media | TVs, streaming devices | medium |
+| lock | Smart locks | high |
+| sensor | Motion, door/window sensors | low |
+| diy | ESP32, Raspberry Pi | high |
+| mixed | Multi-function devices | high |
+
+## Risk Scoring
+
+Risk score is calculated as:
+
+```
+score = base_risk + anomaly_penalty + cloud_penalty
+```
+
+- **base_risk**: 20 (low), 50 (medium), 80 (high) based on vendor/class
+- **anomaly_penalty**: +10 per unresolved anomaly
+- **cloud_penalty**: +10 if >10 cloud deps, +20 if >20 cloud deps
+
+## Anomaly Types
+
+| Type | Severity | Description |
+|------|----------|-------------|
+| bandwidth_spike | high | Traffic Nx above baseline |
+| new_destination | low | First connection to domain |
+| port_scan | high | Contacted many ports quickly |
+| time_anomaly | medium | Activity at unusual hours |
+| protocol_anomaly | medium | Unexpected protocol usage |
+
+## OUI Database
+
+IoT Guard includes an OUI database for ~100 common IoT manufacturers:
+
+- Ring, Nest, Wyze, Eufy (cameras)
+- Philips Hue, Lifx, Wiz (lighting)
+- TP-Link Kasa/Tapo, Tuya (plugs)
+- Amazon Echo, Google Home (assistants)
+- Espressif, Raspberry Pi (DIY)
+- Samsung, LG, Roku (media)
+
+Add custom OUIs to `/usr/lib/secubox/iot-guard/iot-oui.tsv`:
+
+```
+AA:BB:CC	MyVendor	camera	medium
+```
+
