0.1.0 (2025)

load_and_align: automatic MALDI + H&E registration using cv2.warpAffine with full 360° rotation search
add_qupath_annotations: add QuPath GeoJSON annotations to an existing sdata object
graphpca_spatialdata: PCA with optional spatial smoothing via graph Laplacian
get_kmean_clusters: k-means clustering on GraphPCA scores
Add_Pseudo_Image: create spatial images from obs columns
launch_landmark_gui: interactive napari landmark alignment tool
normalize_spatialdata: TIC and RMS normalisation
he_spatialdata: load H&E images as SpatialData objects

load_and_align now uses cv2.warpAffine for canvas construction (replacing PIL rotate), ensuring annotation and image coordinates are derived from the same matrix
_transform_geojson signature changed: takes M_stored directly instead of individual rotation parameters
