Add ZIP-based .invk file format to save and restore the entire canvas state including all layers, masks, reference images, generation parameters, LoRAs, and embedded image files. Images are deduplicated on load - only missing images are re-uploaded from the project file. - Always clear LoRAs on project load, even when project has none - Fix jszip dependency ordering in package.json - Add useAssertSingleton to SaveCanvasProjectDialog for consistency - Add concurrency limit (max 5) for image fetch/upload requests - Remove redundant deep-clone in remapCroppableImage (mutate in-place) - Default project name to "Canvas Project" instead of empty string

There was a problem hiding this comment.
Works and is pretty robust to my testing.
We should also look at intercepting ctrl+s when interacting with a canvas to bring up the save window. That can be down the road when we decide what is going on with UI tabs though.

…le utility Remove the local collectImageNames from useCanvasSnapshots and reuse the shared, more comprehensive version from canvasProjectFile.ts that was introduced by the canvas project save/load feature (invoke-ai#8917). Snapshots don't include global ref images, so an empty array is passed for that parameter. Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]>
