后端： 1.阶段 5 course 服务边界落地 - 新增 cmd/course 独立进程入口，落地 services/course dao/rpc/sv - 新增 gateway/client/course、shared/contracts/course 和 shared/ports course port - 将 /api/v1/course/* HTTP 门面切到 course zrpc，gateway 只保留鉴权、限流、幂等、文件读取和响应透传 - 保留 course 迁移期直写 schedule_events / schedules 权限，维持课程导入两个表同事务写入语义 - 为 course parse-image 补 bytes RPC 契约和 gRPC 消息大小配置，兼容课表图片上传 - 补充 course.rpc 示例配置与阶段 5 文档基线、切流点、残留依赖和 smoke 记录
