060625dfy/dsh-prompt-boost

Trae-style input booster for the dsh web GUI: a sparkle (✨) button beside the model selector optimizes the typed draft into a high-quality, faithful, directly executable prompt via the session's default model; after optimization the button becomes an undo (↩) icon that restores the original input. Zero-build pure-JS plugin: the host half serves /api/prompt-boost/optimize (llm.stream), the browser half registers the conversation.input.right slot.
