altamkp/dsh-middle-click

Middle-click closes a session or a sidebar tab in the DeepSeek Harness Web UI. A session closes through the row's own archive action, so the confirmation for running work and the undo notice stay exactly as the Harness renders them; a tab closes through its own close control, leaving the rule that a lone guide tab cannot be closed untouched. The gesture settles on press-and-release on the same element, so a middle drag never closes anything. Two switches on the plugin's own Settings tab turn each half off, remembered per browser.
