Use opt-in package-data approach to control what goes into wheels: - Set include-package-data = false to prevent MANIFEST.in auto-inclusion - Explicitly include only .pxd files (for downstream cimport) and headers cuda_core wheel size reduced from ~5 MB to ~1.6 MB (68% reduction). Also fix MANIFEST.in for both packages to include all files needed for sdist builds (headers, template files). Co-authored-by: Cursor <cursoragent@cursor.com>

Summary
Use opt-in package-data approach to control what goes into wheels, significantly reducing wheel size:
include-package-data = falseto prevent MANIFEST.in auto-inclusion.pxdfiles (for downstream cimport),.pxifiles (included by.pxdfiles), and required headerscuda_core wheel size reduced from ~5 MB to ~1.6 MB (68% reduction)
Closes #766
Changes
cuda_core:
MANIFEST.in: Added_includeheaders for sdist buildspyproject.toml: Opt-in package-data for.pxdand headers onlycuda_bindings:
MANIFEST.in: Added template files (.pyx.in,.pxd.in,.pxi.in) and.hfor sdistpyproject.toml: Opt-in package-data for.pxd,.pxi(needed because.pxdfiles useincludedirectives), and headersWheel contents after change
Included:
.so/.pyd(compiled extensions).py(Python source).pxd(for downstreamcimport).pxi(cuda_bindings only - required by.pxdfiles that useincludedirectives).pxdfilesExcluded:
.pyx(Cython source).pxi(cuda_core only - these are included from.pyxfiles, not.pxd).cpp(generated C++ files).pyx.in,.pxd.in,.pxi.in)Test plan
