DeepSeek Harness Plugin: dsh-skill-trail

dsh-skill-trail is a DeepSeek Harness (DSH) plugin designed to render compact skill and tool usage trajectories beneath each assistant reply, using engine logs rather than model self-reports. It supports structured data display, replay, and collapsing, and depends on DSH version `>= 0.1.0-rc.6`. It has since been superseded by `dsh-skill-ledger` and archived, with only design history records retained.
