feat: 适配 DSH 命名契约重命名（jobs/terminal/webServer）并处理 Session log 按钮位置

- tasks→jobs：ctx.jobs / job_output / job_id / session/jobs / jobsBySession / Job* 词汇
- httpServer→webServer（inject + augmentation + register/registerUpgrade）
- autoOpenTasks→autoOpenJobs 偏好键
- 右上角开关簇回到角落，注入 CSS 挤开 header 的「Session log」胶囊
