Support all three .dat encryption formats:
- Old XOR format: single-byte XOR, auto-detect key from magic bytes
- V1 format: AES-ECB with fixed key (md5("0")[:16]) + XOR tail
- V2 format (2025-08+): AES-128-ECB + raw middle + XOR tail
New files:
- decode_image.py: unified image decryption module (XOR/V1/V2)
- find_image_key.py: extract AES key from WeChat process memory
- find_image_key_monitor.py: continuous monitoring version for key capture
monitor_web.py changes:
- Inline image preview in Web UI with async decryption
- MonitorDBCache for mtime-based DB decryption caching
- username-to-DB mapping for image resolution chain
- /img/ endpoint for serving decoded images
- SSE image_update events for real-time preview updates
