0.3.1

Hotfix for 0.3. If you downloaded 0.3 on 2026-06-25, please download this version instead.

Changes:

• fixed the Magic Home/Zengge AT OTA trigger URL to use the phone's actual IP address instead of a hardcoded address
• changed the AT OTA version parameter to a universal beta_33_00_ZG-BL form verified with both old and new Zengge firmware
• keeps the Zengge/ZJ OTA header patching, CozyLife TCP/5555 trigger, and standard/small OpenBeken firmware images from 0.3
