Refactor Crop-Clips.ps1 to use table-driven crop profiles for LTX-2, Kling and Wan resolutions, add -Vertical parameter to Create-PillarBox.ps1 for 9:16 portrait output from square sources with horizontal bars, update Resolve-Size to check both dimensions when selecting presets and transpose named sizes in portrait mode, and update README to reflect consolidated cropping functionality
