dsh-tea-set: Tea Set Matching Solutions

The `dsh-tea-set` plugin for DSH (DeepSeek Harness) encapsulates tea set pairing logic to provide domain-specific tooling services for agents. Maintained by uckkk, it registers the `tea_set` tool, which users can install via a command and invoke directly in a conversation. As a pure Node.js implementation, it has no network dependencies at runtime, though users are advised to review the source code and license before installing.
