release(golden): 托底线整体替换为生产实装版原样复制（v26.1.0.3）并重编 B 槽固件

- 生产仓库（GitLab ceramixnano_eddy_cmake_vscode dev@151828f，已在机器上实装）原样复制 8 文件：Src/command.c、i2c.c、ldc1612.c、tmp112.c；Inc/command.h、i2c.h、ldc1612.h；CommunicationProtocol.md（copy 后 fc 逐字节核验一致）
- 保留 B 槽专属构建（LD 0x0800B000/0x4BF8、VTOR 0xB000、gap-fill 0xFF、BUILD_VARIANT=golden），仅 VERSION_PATCH 2→3 对齐生产
- 与 dev 线从此的功能差异属预期（勿"修复"）：LDC1612 驱动电流 GEN(8)（生产 2026-03-23 调参，dev 线仍 GEN(18)）、命令集 M1~M4+M999/M9999（无 M5/M6）、M4 无符号温度算法、旧 8 位寄存器地址 i2c 驱动（配套 tmp112/ldc1612 整组生效）；IIC 新驱动留待后续 A 线版本
- 保底判定值 v26.1.0.2 → v26.1.0.3；两个版本号均永不再用于 OTA 升级包；dev 线后续 A 版本必须 > V1.0.3（当前 dev 同为 V1.0.3，正式发布前须升版）
- 重编译：text+data = 12,036B；向量表校验通过（复位向量 0x0800CC2C 落 B 槽）
- FACTORY 工厂镜像（BL EDDY V0.1.0 + B 满槽 + flag，A 擦除态）已打包：Build\golden\CeramixNano-EDDY_FACTORY_B-V1.0.3_2026-10-25.bin，12 项字节校验全过
