5956a952a0 Migrate build system from Intel oneAPI to AMD AOCC/AOCL toolchain 
- Add TOOLCHAIN=aocc option with flang/clang++/mpicxx compilers
- Replace Intel flags (-xHost/-fma/-ipo/-qopenmp) with AOCC flags
  (-march=znver5/-ffast-math/-flto/-fopenmp) targeting EPYC 9755
- Replace Intel oneMKL with AMD AOCL (BLIS + libFLAME + amdlibm)
- Replace Intel TBBMALLOC with system jemalloc
- Change MKL-specific headers to standard CBLAS/LAPACKE
  (TwoPunctures.C, gaussj.C)
- Guard TBBMALLOC to Intel toolchain only

cb252f5ea2 Optimize numerical algorithms with Intel oneMKL 
- FFT.f90: Replace hand-written Cooley-Tukey FFT with oneMKL DFTI
   - ilucg.f90: Replace manual dot product loop with BLAS DDOT
   - gaussj.C: Replace Gauss-Jordan elimination with LAPACK dgesv/dgetri
   - makefile.inc: Add MKL include paths and library linking

   All optimizations maintain mathematical equivalence and numerical precision.
