dsh-reqtrace: The DSH plugin for reconciling requirements and tool evidence

dsh-reqtrace is a DSH plugin (admin-security class) maintained by xingyanghaifu, designed for session requirement-to-evidence auditing. It reads the agent's todo_write list every 2 seconds, extracts 3–8 acceptance criteria from the user request, and maps each requirement to the actual tool calls, files, and commands within the session, auditing for conflicts between sub-agents and files. It supports manual command verification per requirement, sending "Fix with evidence" back to the agent for gaps, exporting JSON/Markdown reports, and offering two audit modes (direct/subagent) with strict guidance. The ledger is stored locally without reporting telemetry, and verification commands undergo DSH tool approval without automatic execution.
