Multi-image drag-and-drop broken — only first image attached

Bug Description

Dragging and dropping multiple images at once into Claude Code only attaches the first image. The remaining images are silently dropped.

Steps to Reproduce

1. Select multiple images (2+) in file manager
2. Drag and drop them into the Claude Code input area
3. Only the first image appears as an attachment

Expected Behavior

All dragged images should be attached and sent as part of the prompt, similar to how multi-image paste/attach works in other chat interfaces.

Actual Behavior

Only the first image is attached. No error message or indication that other images were dropped.

Environment

• Claude Code version: v2.1.85
• Plan: Max
• OS: Linux (Ubuntu)
• Note: v2.1.85 changelog includes a trailing-space fix for [Image #N] placeholder on paste, but does not address multi-image drag-and-drop

Impact

This forces users to drag images one at a time, which is tedious for workflows that involve sharing multiple screenshots (e.g., UI reviews, bug reports with multiple screenshots, design comparisons).
