dsh-session-doctor: Session Diagnostics and Repair Plugin

`dsh-session-doctor` is a memory management plugin for DeepSeek Harness, designed to automate the handling of anomalies and corruption in session data. Maintained by user luoxin10086, the plugin provides session health checks and repair capabilities, but users must obtain installation instructions from GitHub on their own. When using it, attention should be paid to permission isolation, and the license compliance of the source code should be confirmed. This tool provides an effective automated exception handling solution for DSH scenarios that maintain complex session states.
