dsh-llm-approver: DeepSeek Harness Sandbox Upgrade Pre-Review Plugin

`dsh-llm-approver` is a plugin for DeepSeek Harness designed to use an LLM to pre-approve sandbox escalation requests, reducing the need for manual confirmation. The plugin operates under a specific permission preset and uses an isolated context to evaluate command safety, automatically allowing clearly safe operations and falling back to UI approval for complex or dangerous ones. Installation and configuration are completed through official scripts and `cordis.patch.yml`, with support for multiple Profile adaptation. When using it, you need to switch to the “Workspace Write · LLM Review” preset. The plugin runs with host permissions; any pre-approval failure or timeout is downgraded to manual handling, and complete audit logs are retained.
