DeepSeek Harness Litefuse Plugin: Agent Observability and Evaluation

The Litefuse plugin is the official observability plugin for DeepSeek Harness, designed to address tracing challenges when debugging complex workflows and subagent invocations. It transforms DSH runtime data into Litefuse-compliant traces, supporting turn-level mapping, subagents, code modes, and zero-dependency OTLP integration. By installing it via `npx` and configuring the public and private keys in environment variables, users can view real-time execution details on the Litefuse platform, including latency, token usage, and context compression events. The plugin runs with the permissions of the current process, reads environment variables by default, and strictly safeguards key security.
