Problem

Generated/resized OG images are stored in images/mokoog/generated/ with no eviction or cleanup mechanism. ImageHelper::cleanup() exists but is never called anywhere in the codebase.

On sites with many articles, this directory grows indefinitely.

Fix

Options (pick one or combine):

Wire up ImageHelper::cleanup() to a Joomla scheduled task (plg_task_*)
Add an admin "Purge Cache" button in the component toolbar
Add a CLI command (php cli/mokoog.php cleanup)
Implement TTL-based auto-eviction (delete images older than N days)

Files

source/packages/plg_system_mokoog/src/Helper/ImageHelper.php:154-165 (existing cleanup method)
source/packages/plg_system_mokoog/src/Helper/ImageGenerator.php (generates images)

Low priority — ImageHelper::cleanup() exists but has no callers. ImageGenerator::generate() also has no callers. Cache growth is theoretical until image generation is wired into a workflow. Can address when image generation is actually activated.
