--------------------------+-----------------------------
 When WordPress generates image thumbnails using ImageMagick, the
 `writeImage()` method in `wp-includes/class-wp-image-editor-imagick.php`
 causes duplicate `CLOSE_WRITE,CLOSE` inotify events.
 Steps to reproduce:
 1. Upload an image to WordPress
 2. Monitor inotify events: `inotifywait -m -e close_write /wp-
 content/uploads/`
 3. Observe duplicate events for each thumbnail

 Expected behavior:
 One `CLOSE_WRITE,CLOSE` event per thumbnail file

 Actual behavior:
 Two `CLOSE_WRITE,CLOSE` events per thumbnail file

 Root cause:
 The `writeImage()` method performs internal buffering that creates two
 file operations:
 1. Write data to buffer
 2. Flush buffer to file

 Proposed fix:
 Replace `writeImage()` with `getImageBlob()` + `file_put_contents()` for
 single operation.

 Files affected:
 - wp-includes/class-wp-image-editor-imagick.php (line 976)
