chore: 初始开源发布

iotlcm-worker-svr：异步执行中枢（RabbitMQ 消费者 + 全量同步编排）。 - Go module：iotlcm-worker-svr → git.5iot.com/iotlcm-public/iotlcm-worker-svr（214 文件） - 凭据与内部标识脱敏：MySQL/Redis 凭据、私网与生产 IP、内网域名、库名 xiujie_admin → iotlcm、哨兵名占位 - 159 处真实手机号 → 合法 11 位编造号（保留号段与后 4 位，维持互异，不破坏「校验 MSISDN 格式」等测试断言） - 移除内部资产：CI 触发器、Jenkins 触发测试文档、预演门禁与镜像 digest 记录 - Dockerfile 改用公共基础镜像（golang:1.25-alpine → alpine:3.23），移除写死的 git 凭据 - README 重写（架构/全量同步模型/配置/已知失败），补 Apache-2.0 LICENSE，LF 行尾 + .gitattributes 已知：3 个测试包在源仓同一提交上同样失败（client/upstream、 service/allocate、service/inbound），属既有缺陷，本仓未引入亦未修复。
