Add GIF, Krea, and Set/Get workflow tools

Add timed GIF load, stitch, and save nodes; modular Krea 2 editors and prompt encoders; a downscale node; and compatible Set/Get frontend nodes. Also improve video-save progress and chooser positioning, update schema and release checks, and bump the package version to 3.3.1.
