dsh-australia: Australia Country Info Plugin

`dsh-australia` is a DeepSeek Harness (DSH) plugin maintained by developer uckkk, focused on providing basic information about Australia. Built with pure Node.js, it has no runtime network dependencies and a clear code structure. It aims to simplify workflows involving the processing and querying of Australia-related data in AI agent development, making it suitable for restricted network environments. The installation command is `dsh plugin add github:uckkk/dsh-australia`. Developers should note that the plugin runs with the current DSH process permissions and should review its source code and MIT license.
