Codex-style drag-to-reference for DeepSeek Harness: drag a conversation row from the sidebar onto the chat area and it becomes a native session-reference chip in the composer draft, so you can keep typing around it before sending. Drag a workspace (folder) row instead and the draft gets that folder's path, so a whole directory can be handed to the model. The target session is matched by session id rather than by title, so duplicate or blank titles cannot insert the wrong conversation. The reference cap comes from the host (3 by default) and is read at runtime instead of being hard-coded, so a host-side raise is followed without changing the plugin. If the chip cannot be inserted, the plugin falls back to sending a reference-only message instead of failing silently.
