dsh-plugin-verified-search: Bounded Connected Verification Workflow with Auditable Evidence

The DSH workflow plugin maintained by Chih-Kai-Wang replaces `web_search` with a bounded workflow to display in-session scope sources, retained citation excerpts, and unresolved gaps. The stable track v0.1.1 provides `verified_search`, while experimental snapshots additionally include four categories of JSON/research tools. It requires Harness 0.1.1-rc.2, Cordis 4.0.1, and a searchable preset, and is installed via a web profile. This article organizes installation commands, quickstart, and applicable boundaries based on the GitHub README and explains compatibility with Discussions #332/#344 and the dsh-web ecosystem.
