dsh-antigua: Antigua and Barbuda Information Query

dsh-antigua is a localized country information plugin under the DeepSeek Harness (DSH) concept, designed to address network latency when retrieving metadata for a specific country. Maintained by user uckkk, it provides a pure Node.js implementation for querying static information about Antigua and Barbuda, such as its capital, population, currency, and continent, returning results quickly without an internet connection. This plugin depends on a specific version of the DSH tooling library and is suitable for latency-sensitive agent scenarios or those requiring offline operation.
