dsh-cap-profile: DSH Model Capability Profile Plugin

dsh-cap-profile is a visualization plugin for DeepSeek Harness that transforms local session history into capability profiles and error-rate dashboards. It supports filtering by model and time, provides model comparison tables and top-5 analyses of tools and error signatures, and includes multi-model comparison. The plugin is read-only and does not modify data, using incremental caching to maintain performance, and helps users quickly identify differences in model performance and failure-prone areas.
