dsh-future-quantum-computing: Quantum Computing

The `dsh-future-quantum-computing` plugin for DeepSeek Harness (DSH) is designed for building agents that work with quantum computing data, providing interfaces for accessing entries and their details. Written in Node.js with no network dependencies, it can be invoked directly in a session after installation. Before use, ensure the environment satisfies the `@deepseek-ai/cordis` and `@deepseek-ai/dsh-tools` dependencies. The plugin offers two core features: `list_qc` for listing entries and `get_qc` for querying details.
