DeepSeek Harness Plugin: dsh-gpt-tool-compat

The DSH plugin `dsh-gpt-tool-compat` is designed to address validation failures caused by third-party model clients appending privilege-escalation parameters in tool calls. During the `tools/pre-execute` phase, the plugin intercepts and strips invalid parameters that would inevitably be rejected (such as empty justification or unpaired fields), while preserving genuinely valid privilege-escalation requests. With fault-tolerance and exception-protection mechanisms, it implements a compatibility layer without bypassing security authorization or affecting normal calls. Installation supports Bundle or direct insertion of a Cordis Patch.
