Simplify Image Processing Design
Goal
Remove obsolete RMagick/MiniMagick integration and collapse mandatory ImageMagick behavior into EasyExtensions::ImageProcessing.
Design
- Preserve six public
EasyExtensions::ImageProcessingmethods andAdapterProcessExceptionbehavior. - Move current
ImagemagickAdapterimplementation intoapp/utils/easy_extensions/image_processing.rbwithout command or return-contract changes. - Delete both adapter modules, adapter selection,
MissingAdapterException, and unreachable rescue branches. - Remove optional MiniMagick loading and admin availability reporting.
- Keep existing locale entries to limit translation churn.
Verification
- Focused RSpec coverage for geometry, conversion delegation, and command-error mapping.
- Focused RuboCop for changed Ruby files.
- Repository search proving removed constants have no remaining code references.
