feat: ESP32-S3 双核并行摄像头系统 (AsyncUDP + ESP-NOW)

- 主程序: src/main.cpp - AP模式摄像头推流 + AsyncUDP中断通讯
- 通信模块: UDPPeer类 (UDP + ESP-NOW双通道, Flash配置持久化)
- 参考实现: ESPNOW通讯 / bkespnow版本 / 普通连接版本
- clangd配置: --target=arm-none-eabi + __XTENSA__宏 + 工具链sys-include
- 硬件: ESP32-S3-WROOM-1-N16R8 + OV2640, 16MB Flash, Octal PSRAM
