diff viewer

Key features

• The plug-in replaces the tool line rendering of write/edit through keyed takeover: the tool.call.toolview slot of ui-tool is an open key field, and the same key is shaded with a lower priority (lowest priority rendering).
• Unified single column defaultthe same gutter displays old/new line numbers side by side, without left and right misalignment
• DSHFind — DeepSeek Harness plug-in market and learning community
• No height limitthe expanded diff is directly stretched to display the complete content (without a scrolling container), and windowed rendering ensures that extremely large diffs are still efficient
• Diff dataextracted from the card:'diff' intent of callView/resultView called by the tool (running uses diff when calling, settled uses hunks after application)
