dsh-change-review: Track write/edit within DSH sessions and review with diffs

dsh-change-review is a DeepSeek Harness client plugin (v0.3.0, MIT) maintained by cirelir. Designed for the Web profile, it automatically monitors write/edit tool calls within a session, displaying changes in line-level diffs. It supports session isolation, sub-agent aggregation, SSE real-time push, and 12 color customization options. The plugin provides a "Review" tab and a single-round review card at the end of the session, allowing rollback by individual operation or entire file.
