DeepSeek Harness Issue Reporter Plugin

`dsh-issue-reporter` is a DeepSeek Harness plugin designed to address the cumbersome process of submitting high-quality bug reports during autonomous workflows or plugin failures, as well as the risk of sensitive information leaks. It provides a visual interface and integrates features such as automatic sensitive-data masking, duplicate detection, AI-optimized descriptions, automated diagnostics, and screenshot upload. The plugin supports GitHub OAuth authentication and manages issue creation and search through the `repo` scope. It also exposes API endpoints for automated calls by agents, and supports batch querying of issue status and intelligent label recommendations, ensuring standardized and efficient submissions.
