Rebuild ImageAutosize to use ComfyUI V3 node API: add a proper ComfyExtension entrypoint and io.Schema-based node. Rename display to "Image/Mask Autosize", accept IMAGE or MASK inputs, and replace multiplier output with scale_x/scale_y. Add constraint_priority (min_size/max_size), anchored crop handling, divisible-by rounding protection, and new interpolation modes. Update README, add CHANGELOG, bump package version to 0.2.0, refresh workflow image, and include comprehensive unit tests for sizing, cropping, and mask behavior.
