DSH Plugin dsh-longtask-orchestrator: Long Task Orchestration

The `dsh-longtask-orchestrator` within the DSH plugin ecosystem is an orchestrator plugin designed specifically for long tasks and follows the MIT license. It adopts a multi-model collaboration mode, emphasizing the philosophy of "everything is a plugin": Codex is responsible for planning, scoring, and final review, DSH handles specific execution, and Kimi manages summaries, cross-validation, and visual acceptance. The plugin decomposes long tasks into standard steps, including initialization, plan generation, subtask execution, result scoring, supplementary validation, and final review. It registers a total of 9 tools and supports the automatic triggering of loop templates via skills. Installation requires using a local link command and restarting the DSH web interface. Typical usage includes switching to a specific model group, initializing the task, executing subtasks according to a checklist, iterative scoring, and final review. In terms of configuration, Codex defaults to invoking local binary files and performs auto-detection.
