dsh-maze: The Execution Maze for DeepSeek Harness

`dsh-maze` is an execution-maze visualization plugin for DeepSeek Harness (DSH), formerly known as `dsh-trace-compare`, designed to debug and evaluate agent behavior. It renders an agent’s execution process as a timeline-based maze, intuitively displaying the main path, failed branches, and backtracking points. Core features include data tracks (tool-call density, token consumption, and context pressure), deterministic execution analysis (failure recovery chains and tool result matrices), and multi-session comparison. The tool supports real-time replay, view export, and Chinese/English bilingual support, helping developers deeply understand agent logic and efficiently troubleshoot long-chain issues.
