dsh-sub-audit: Subscription Audit

`dsh-sub-audit` is a subscription audit plugin for DeepSeek Harness (DSH), maintained by uckkk. It addresses the lack of real-time subscription source validation for developers by enabling precise calculation and detailed auditing of subscription parameters. The plugin is implemented in pure Node.js with no network dependencies. Developers can install it via a command and invoke its features in a session to audit subscription content. It runs with the privileges of the current process, and users are advised to review the MIT license.
