moldkey/dsh-deepseekbase: Integrate DeepSeek pricing, model specifications, and plugin retrieval into Harness.

moldkey/dsh-deepseekbase is a DSH model inference plugin released by moldkey, the maintainer of the third-party index site deepseekbase.com. It provides four tools within a session: deepseekbase_price to check prices and compare providers, deepseekbase_plugin to retrieve plugins, deepseekbase_specs to check model specifications and context lengths, and deepseekbase_trend to check usage trends. During runtime, the plugin only sends HTTPS requests to deepseekbase.com. The implementation is centralized in lib/index.js, has no runtime dependencies, and does not access local files or credentials. It can be installed using `dsh plugin --profile web add github:moldkey/dsh-deepseekbase` and takes effect after restarting. It requires `engines.dsh` >= 0.2.0-rc.2, with the npm package name `@liangjiehappy/dsh-deepseekbase`. It is suitable for quickly comparing provider pricing and selecting models based on context length within a session. It is recommended to review the source code and verify the MIT license before installation.
