dsh-cape-verde: Cape Verde National Information Lookup Tool

The DeepSeek Harness (DSH) plugin dsh-cape-verde embodies the "everything is a plugin" philosophy and is used for locally querying information about Cape Verde. Maintained by uckkk, it registers the `country_info` tool to retrieve basic information such as Cape Verde's capital, population, currency, and continent without network requests. Installation requires `@deepseek-ai/cordis` and `@deepseek-ai/dsh-tools`, and it is implemented in pure Node, making it suitable for offline or lightweight environments.
