dsh-timor-leste: Timor-Leste Information Query Plugin

`dsh-timor-leste` is an online tool plugin for DeepSeek Harness (DSH) designed to address the challenge of agents retrieving geographic metadata for Timor-Leste. The plugin encapsulates basic information about the country, including its capital, population, currency, and continent. As a pure Node.js implementation, it can be used without network requests. Developers can install it via the terminal and directly invoke its `country_info` tool within a session. It is suitable for DSH agent development that requires integrating Timor-Leste geographic data, but environment dependencies and security reviews should be considered before installation.
