review-quote-sh: dsh web multi-model cross-review and citation Q&A plugin

# Introduction When collaborating with models via dsh web, two common issues often arise: first, reviewing code or conclusions generated by the AI often requires switching tools and pasting content back and forth, which is cumbersome; second, attempting to continue a conversation based on a specific reply requires manually copying the original text as context, which can easily lead to confusion in long dialogues. The `review-quote-sh` introduced below is designed for these two scenarios: it adds multi-model cross-review and cited Q&A capabilities to dsh web. Following DSH's philosophy of "everything is a plugin," it is implemented as a hot-swappable profile bundle without modifying the core system. # What is it The `review-quote-sh` is a Dialogue Review + Citation tool for DeepSeek Harness (dsh web).
