Bug fixes, stabilization and performance improvements.

This version notable bugfixes: - Fix loading of TIFF files with JPEG compression - Fix crash when undoing liquify - Fix crash when using a smudge brush

This version brings back thumbnails and previews for krita files. Also it brings a fresh icon that integrates with macOS Tahoe appearance. Also we have a new look and feel for the color picker preview. Previously, we used two rectangles side by side. This was a little annoying for righthanded folks, as the squares veered off to the right. Now, we provide a circular preview by default, and you can customize the size of the preview. Or just go back to two rectangler side by side! Other bugfixes: - Fix brush preview outlines being aligned based on incorrect bounding box. [Bug 477164] - Fix off-by-1 in BrushHud Deform Modes combobox [Bug 509741] - Double-click slider spin boxes to edit - Allow long-pressing to open context menus - Enable double and triple click with stylus when using vector tools. - Add toggle eraser preset touch canvas input - Properly calculate long-press slop distance - Make long-press context menus behave more cleanly - Fix various touch shortcuts with wrong actions [Bug 485161] - Make sampler preview not rotate/mirror with canvas [Bug 347799] - PythonPluginManager: Fix crash on Python 3.14 - Update krita app icon to display in respect to system appearance (Tahoe) - Make thumbnails of kra, krz and ora [Bug 493474] - Don't allow dragging layers onto their own canvas [Bug 512771] - Allow holding Ctrl to override drag on canvas - Fix crash when using a smudge brush [Bug 512243]
