Prompt Enhance

Description

Prompt enhancement (DSH general-purpose plugin): Three modes (Basic/Standard/Expert) read the session workspace project context and call an LLM to enhance prompts in the input box. Supports result comparison and confirmation, undo after adoption, a fallback chain for failed models, automatic adaptation of reasoning levels based on model capabilities (automatically retries without the parameter when the gateway does not support it), a pending-confirmation Q&A loop (re-enhances with answers after each question is answered), configurable composite-row config, and cancellation. The Host half provides /api/prompt-enhance/enhance; the browser half registers mode selection and a ✦ button, a comparison panel, and a busy-state card in the composer toolbar. Automatically loads when harness starts; no manual reload required.
