DSH Too Long Warning

`dsh-toolong-warning` is a plugin for DeepSeek Harness (DSH) designed to address pain points in context window management. It tracks conversation compaction events and issues a warning only when compactions are frequent and involve significant additional token consumption, preventing unnecessary interruptions to users. The plugin provides a draggable, bilingual floating window and supports customizable trigger thresholds, helping developers identify cost-inefficient conversations while balancing context management with cost. Installation requires DSH 0.1.7-rc.1 and Node.js 22.19 or later.
