feat(dpi): Phase 2 - MITM double buffer + LuCI dashboard

MITM Double Buffer (dpi_buffer.py):
- Compiled regex patterns for 6 threat categories
- Scanner detection (sqlmap, nikto, nmap, etc.)
- Optional blocking mode for high-score threats
- Request replay queue for forensic analysis
- Rate limiting detection
- Stats: buffer entries, threat distribution, top hosts

LuCI Dashboard (luci-app-dpi-dual):
- RPCD handler with 10 methods
- KISS-themed overview with stream status cards
- LED indicators for MITM/TAP/Correlation
- Threats table with score and blocked status
- Protocol distribution from netifyd
- Manual IP correlation trigger

Streamlit Control Panel:
- Added DPI Dual card with flows/threats/blocked metrics

-- **Dual-Stream DPI Architecture (Phase 1 Complete)**
+- **Dual-Stream DPI Architecture (Phase 2 Complete)**
   - New `secubox-dpi-dual` package implementing parallel MITM + Passive TAP DPI
   - Architecture doc: `package/secubox/DUAL-STREAM-DPI.md`
-  - **TAP Stream (Passive)**:
+  - **Phase 1 - TAP Stream (Passive)**:
     - `mirror-setup.sh`: tc mirred port mirroring (ingress + egress)
-    - Creates dummy TAP interface for netifyd analysis
+    - `dpi-flow-collector`: Aggregates netifyd stats → `/tmp/secubox/dpi-flows.json`
-    - Software and hardware TAP mode support
+    - `dpi-correlator`: Matches MITM + TAP events, CrowdSec integration
-  - **Flow Collector**:
+    - `dpi-dualctl`: CLI start/stop/status/flows/threats/mirror
-    - `dpi-flow-collector`: Aggregates netifyd flow statistics
+    - `init.d/dpi-dual`: Procd service for flow-collector + correlator
-    - Writes stats to `/tmp/secubox/dpi-flows.json`
+  - **Phase 2 - MITM Double Buffer + LuCI**:
-    - Interface stats from /sys/class/net
+    - Enhanced `dpi_buffer.py` mitmproxy addon:
-    - Configurable flow retention cleanup
+      - Compiled regex patterns for 6 threat categories (path_traversal, xss, sqli, lfi, rce, ssrf)
-  - **Correlation Engine**:
+      - Scanner detection (sqlmap, nikto, nmap, etc.)
-    - `dpi-correlator`: Matches MITM + TAP stream events
+      - Optional blocking mode for high-score threats
-    - Watches CrowdSec decisions and WAF alerts
+      - Request replay queue for forensic analysis
-    - Enriches threats with context from both streams
+      - Rate limiting detection
-    - Output: `/tmp/secubox/correlated-threats.json`
+      - Stats: buffer entries, threat distribution, top hosts
-  - **CLI Tool**:
+    - **LuCI Dashboard** (`luci-app-dpi-dual`):
-    - `dpi-dualctl`: start/stop/restart/status/flows/threats/mirror
+      - RPCD handler with 10 methods (status, flows, buffer, threats, correlation, start/stop/restart, replay, correlate)
-    - Shows unified status of both streams
+      - KISS-themed overview with stream status cards
-  - **Procd Service**:
+      - LED indicators for MITM/TAP/Correlation running state
-    - `init.d/dpi-dual`: Manages flow-collector and correlator instances
+      - Metrics: buffer entries, threats, blocked, flows/min, RX/TX bytes
-    - Auto-starts based on UCI mode setting (dual/mitm-only/tap-only)
+      - Threats table with timestamp, IP, host, path, categories, score, blocked status
-  - **MITM Double Buffer (Phase 2 prep)**:
+      - Protocol distribution from netifyd
-    - `dpi_buffer.py`: mitmproxy addon for async analysis
+      - Manual IP correlation trigger
-    - Ring buffer with configurable size (1000 requests default)
+      - ACL permissions for read/write
-    - Heuristic threat scoring (path traversal, XSS, SQLi, LFI patterns)
+    - **Streamlit Control Panel** updated:
-    - Writes threats to `/tmp/secubox/waf-alerts.json`
+      - DPI Dual card with flows/min, threats, blocked metrics
-  - **UCI Config**: `/etc/config/dpi-dual` with global, mitm, tap, correlation sections
+      - Reads from dpi-buffer.json and dpi-flows.json caches

-DPI Double Buffer Addon for mitmproxy
+DPI Double Buffer Addon for mitmproxy - Phase 2
 Part of secubox-dpi-dual package
 
 Implements the double-buffer pattern:
 - Buffer A: Live path, minimal latency (default mitmproxy behavior)
 - Buffer B: Copy for deep analysis, async processing
 
-This addon queues requests for asynchronous analysis without
+Features:
-blocking the live traffic path.
+- Ring buffer with configurable size
+- Async threat analysis without blocking
+- Request replay capability for forensic analysis
+- Context gathering for correlated threat investigation
+- Stats endpoint for monitoring
