lightflow-image-upscale

# LightFlow Image Upscale Use `lightflow.image_upscale` to enlarge a PNG image by an integer scale factor. ## Workflow - Workflow id: `lightflow.image_upscale` - Runtime ownership: this workflow crate owns its public `execute()` entry and exposes it through the `lightflow-image-upscale-runner` package binary. - Host engine: `package.command.v1`; discovery, help, and plan do not execute package source. - Input values are validated against their declared JSON types without string coercion. - Runtime: `lightflow.image.upscale`. - Input `image_path`: required source PNG path; artifact kind `image`; widget `image`. - Input `scale`: optional integer; default `2`. - Outputs `image` and `image_path`; artifact kind `image`. ## Usage ```bash lfw run lightflow.image_upscale -i image_path=./input.png -i scale=2 ``` ## API Usage Start `lfw serve`, then call the workflow through the shared HTTP run contract. Adjust `inputs` to match the workflow contract above. ```bash curl -sS -X POST http://127.0.0.1:5174/workflows/lightflow.image_upscale/run \ -H 'content-type: application/json' \ -d '{"inputs":{}}' ```
