Add Hookify hooks to detect and prevent problematic drag-and-drop image operations that cause Claude Code to freeze on 'pasting text...'. - Block reads from macOS temporary folders that contain incomplete thumbnails - Warn users before reading image files to prevent hangs - Provide helpful guidance for proper drag-and-drop workflow - Reference issue anthropics#55420 for additional context This addresses the root cause where macOS creates floating thumbnails before fully saving files, causing Claude Code to hang when trying to read incomplete/temporary file paths.

Problem
On macOS, dragging and dropping a screenshot into Claude Code
freezes the session on "pasting text..." requiring a full
session restart.
Fixes #55420
Root Cause
macOS creates a floating thumbnail preview before fully writing
the file to disk. When users drag this thumbnail, Claude Code
receives an incomplete or temporary file path and hangs
indefinitely trying to read it.
Fix
