dsh-socrates: DeepSeek Harness Deep Research Plugin

`dsh-socrates` is a deep research plugin for DeepSeek Harness, released under the MIT license. Its core philosophy is “Everything is a plugin.” By introducing Socratic clarification mechanisms and adaptive closed-loop research logic, it addresses the lack of verification in traditional pipelines. The plugin supports pre-research clarification, parallel multi-round research, claim-level cross-validation, programmatic citation auditing, and academic three-source retrieval. Through model-tier scheduling (Pro/Flash), it achieves high-precision deep research and automatically generates documents that include an evidence library and a citation report.
