项目快照按渠道分区，后台项目工程支持渠道筛选与游标分页

项目快照对象键升级为 agc/project-snapshots/v2/{channel}/{user}/{project}/，渠道取部署配置 GENARRATIVE_AGC_PROJECT_SNAPSHOT_CHANNEL（缺省沿用客户端下载渠道），非法渠道在写入处失败关闭
后台新增渠道列表接口，项目工程列表与下载接受 channel，游标绑定渠道并拒绝跨渠道复用
后台项目工程用户列改为素材查询口径：昵称 + 陶泥号 + 用户详情入口，由 api-server 解析作者信息
后台项目工程改为游标分页：每页 20/50/100、上一页/下一页与当前页提示，翻页失败保留当前页
部署环境示例补充快照渠道配置，并同步运维、技术方案、里程碑与决策记录文档
