dsh-risk-guard: Zero-Interruption Audit and Fuse Blocking for DeepSeek Harness

`dsh-risk-guard` is a security plugin for DeepSeek Harness (DSH), designed to address the challenge of quantifying and tracing destructive operations performed by an agent. It replaces ambiguous LLM judgments with a deterministic scoring model, providing silent auditing and circuit-breaker protection for irreversible operations. Its core capabilities include silently recording tool call logs, rule-based zero-interruption risk scoring, and blocking catastrophic actions such as deleting protected paths and force-pushing. The plugin stores audit data in local JSONL files and supports viewing an operation bill via commands, making it suitable for development scenarios that require high agent security.
