Use imageSize() on images, not textureSize(). In GLSL, the LOD parameter to textureSize() is mandatory for sampled textures, so emit a default 0 if not supplied. (Also, don't pack the level into the coords argument; that's an HLSLism.) GLSL returns the array size of array textures in the final component of textureSize(); remove it for WGSL. Write the subtype of storage images correctly (uimage*, iimage*, etc). This required a bit of cleanup to move "writeonly" ahead of subtype emission.
