Fix symbol visibility so shared libs export Fortran wrappers consistently
Resolved inconsistent symbol exports for Fortran wrapper entry points and test helpers across Windows and macOS. Adjusted default visibility in the makefile, added FINUFFT_EXPORT_TEST for test-only APIs, and linked FFT backends via a new finufft_fftlibs interface target. It also adds the LTO option to makefile to achieve parity with cmake. Co-authored-by: Marco Barbone [email protected] Co-authored-by: Martin Reinecke [email protected]
