feat: M2.1 客户端骨架、BLE 修复、仓库整理与现状板

- BLE: 修复 BlueZ LocalName 与 Includes 冲突，串行注册与退避
- HTTP: 语音对话补 Live2D talking 标志与 session；Web 补 X-Session-Id
- Flutter: 角色/对话/模型页 + API，Gradle/依赖升级，麦克风权限
- 文档: 新增 docs/STATUS.md，校准 CLAUDE/PROGRESS/README
- 清理: 移除根目录截图与临时模型，运维脚本迁入 scripts/device

+
+从仓库根目录迁入的临时/运维 shell，供目标机调试用，**非产品运行时依赖**。
+
+| 脚本 | 用途（以内容为准） |
+|------|-------------------|
+| `ssh_check.sh` | SSH 连通检查 |
+| `build.sh` / `run.sh` / `start.sh` | 设备侧编译/启动辅助 |
+| 其余 | 历史探测脚本，用前请先读内容 |
+
+主服务请用：
+
+```bash
+systemctl --user status showen_v2.service
