DSH-Cloak-Browser: Native Browser Plugin for DeepSeek Harness's CloakBrowser

`dsh-cloak-browser` is a community-maintained plugin for DeepSeek Harness (DSH), designed to integrate CloakBrowser capabilities into the Agent tool pipeline. It ensures session security by maintaining an isolated `BrowserContext` for each Agent, and returns restricted page snapshots along with short-lived element references (e.g., `p1:s3:e8`) after interactions such as navigation, clicking, input, and screenshots, enabling the Agent to continue operations based on these references without retaining extensive DOM data. Core features include on-demand Chromium startup, automatic license detection (supporting direct startup with Free keys and serializing concurrent sessions), proxy-aware GeoIP consistency, domain allowlist/blocklist rules, and handling for images and text—
