dsh-live-loop: A Frontend Runtime Verification Plugin for DeepSeek Harness

`dsh-live-loop` is a frontend runtime validation plugin for DeepSeek Harness (DSH), designed to ensure that web applications load correctly and behave as expected by performing detection, interaction, visual comparison, and evidence generation. It does not modify code and is responsible only for the validation process, supporting frameworks such as Vite, React, and Vue while providing isolated environments, bounded observation, and a strict four-state verdict mechanism. It requires DSH version 0.1.0-rc.7 and Node.js 22.19.0+, giving agents a closed-loop capability from detection and remediation to validation to ensure rigor in frontend automation workflows.
