Introduces mediacomparers.py with an Image Comparer + Save MXD node, updates __init__.py to register new node mappings, and adds a frontend widget (image_comparer.js) for image comparison. Refactors and shortens DESCRIPTION strings for clarity across maxedoutnodes.py and wan22nodes.py, adds a ControlNet Preprocessor Selector node, and updates web/index.js to include the new comparer widget.
Deleted the help_popup.js module and its dependencies (marked.min.js and purify.min.js), and removed its import from index.js. This cleans up unused code and dependencies related to the help popup feature.
Simplifies and clarifies the bucket selection logic in WAN22_I2V_Image_Scaler_MXD, ensuring square images always map to fixed square buckets and improving handling for 720p, 480p, and Auto tiers. Also adds a new maxedout_icon.png asset.
