补齐项目快照的客户端上传与后台列表下载联调取证

- 新增 scripts/check-agc-project-snapshot-admin-http.mjs：核对后台列表里的快照统计、下载工程 ZIP、逐条与本地项目副本比对 SHA-256，并检查排除项与 .agent 目录
- 里程碑条目 9 改为已勾选，写入真实客户端共享模块上传（首次 synced、紧接着 no-op）与后台列表/ZIP 的 HTTP 联调取证，并把未验证项单独列出
- pitfalls 记录单用户每小时 3000 次文件上传配额对真实链路冒烟的影响与选项目口径

+// AGC 项目快照「后台列表 + 工程 ZIP 下载」的真实链路检查。
+//
+// 用法（需要本地 dev 栈与一份已经同步过的项目副本）：
+//   E2E_ADMIN_USER=<管理员> E2E_ADMIN_PASSWORD=<密码> \
+//   E2E_SNAPSHOT_USER_ID=<快照归属 user id> E2E_SNAPSHOT_PROJECT_ID=<project id> \
+//   E2E_SNAPSHOT_PROJECT_DIR=<本地项目副本绝对路径> \
+//     npm run check:agc-project-snapshot-admin-http
+//   E2E_API_BASE 默认 http://127.0.0.1:4198；E2E_SNAPSHOT_CHANNEL 默认 dev。
+//
+// 覆盖：管理员列表能看到该快照的统计（status=ready / fileCount / totalBytes）→ 下载 ZIP →
+// 条目数与列表一致 → 每个条目与本地副本同名文件的 SHA-256 逐一致 → ZIP 里没有版本库 /
+// node_modules / .env* 这类被排除的内容。整条链路只读：不写 OSS、不改后台数据。
