I would like to know how the zonal_stats() function from the library rasterstats works, as I am calculating the mean values of a raster within a polygon. If a raster cell touches partially the polygon boundaries, is the whole cell included in the statistics? or is it "clipped" and then calculated? I cannot see a reference in rasterstats documentation.

It's explained in the docs that @Spacedman linked, via the all_touched parameter:

all_touched: bool, optional

Whether to include every raster cell touched by a geometry, or only those having a center point within the polygon. defaults to False
