dsh-task-engine: Task-Level Engineering Workflow for DeepSeek Harness

dsh-task-engine is a workflow plugin for DeepSeek Harness, designed to provide task-scoped engineering support for continuous development projects. It supports adaptive workflows across four complexity tiers, binding of meta-skills to project Skills/Rules, repository initialization, and SonarQube CI review. Through its engineering task ledger and preview creation features, the plugin helps developers standardize their development workflow. After installation, developers can select an appropriate path as needed during a session and reuse team standards via project Skills. Although SonarQube integration has limitations, the plugin improves development efficiency and consistency through a structured process.
