dsh-gov: DeepSeek Harness Enterprise-Grade Governance Suite

`dsh-gov` is an Agent governance suite for DeepSeek Harness, designed to address issues such as high-risk tool invocations, audit traceability, and cost control. The plugin provides policy-based access control (supporting allowlists, blocklists, and priorities), structured audit logs in JSONL format, and per-agent token quota management. It runs with the permissions of the current process, so its source code should be reviewed before installation. Through the `gov` tool, users can configure policies, limit token usage, and query audit records, helping enterprises use DSH securely and in compliance.
