Module hooks/useVisibleImageLoader

useVisibleImageLoader - Hook for visibility-based image URL loading

Fetches image URLs only for recipes that are visible or near-visible in the viewport, dramatically reducing network requests for large recipe lists. Uses debouncing to prevent fetch spam during fast scrolling and supports fetch cancellation.

Key Features:

• Only fetches image URLs for visible/near-visible items
• Debounces visibility changes to avoid fetch spam
• Cancels in-flight fetches for items that leave viewport
• Limits concurrent fetches to prevent memory exhaustion
• Tracks fetched URLs to avoid duplicate requests
