xinstart-1/dsh-files-fallback

File reference & attachment plugin for DeepSeek Harness (DSH) web GUI: drag, paste, or upload files and images of any type; unified storage under .dsh-file-attachment with @absolute-path references so text-only models work; desktop fallback turns folders, oversized or empty files and failed uploads into @path references with zero copy and no size limit; inline file/folder chips, clickable chat thumbnails; for non-multimodal models images are auto-described by a vision model picked from the harness model catalog dropdown (harness models by default, or a custom OpenAI-compatible endpoint via Base URL + API Key); optional session-cleanup sync on session delete.
