fix(report): 报告源/产物落 MinIO,去掉 gateway↔mcp-go 本地盘耦合

多机/容器化第一时间断裂的隐患(ARCHITECTURE_REVIEW §7 #1):此前报告
源(reportStore)与 .docx 产物(reportExport/reportRender)都写 mcp-go
本地 SUNDYNIX_REPORTS_DIR,gateway 再按同一路径 c.File 回流——mcp-go
与 gateway 不共享磁盘即断。

- blob 包从 gateway/internal 提到 sundynix-shared/blob,gateway 与 mcp-go
  共用同一 MinIO;新增 PutBytes/GetBytes 走二进制(.docx)。
- mcp-go 注入 blob:report 源/产物优先 Put 到对象存储(键 reports/<id>.{json,docx}),
  导出结果返回 minio://<key>;MinIO 未就绪回退本地盘(单机降级,getSource 兼容旧本地报告)。
- gateway ExportReport 识别 minio:// → GetBytes 流式下载,否则 c.File 本地降级。
- 测试:mcp 本地回落往返单测 + shared/blob 真 MinIO 二进制往返(BLOB_TEST_ENDPOINT 门控)。
  四模块 build 绿,受影响测试全过。
- 附带:go mod tidy 引入 genproto 拆包冲突,四模块统一钉单体 genproto 新版解决
  (注:勿 go work sync,会剪掉 indirect require 回落旧版重现冲突)。
