{numlib}[lmpich/2025b] FFTW.MPI v3.3.10, lmpflf v2025b, ScaLAPACK v2.2.2 w/ fb

[Thyre]

(created using eb --new-pr)

Requires:

• {toolchain}[lfoss/2025b] Add files for lfoss toolchain 2025b #24514
• Implementing a new LLVM based toolchain easybuild-framework#4914
• {toolchain}[system/system] lompi v2025b, lmpich v2025b, llvm-compilers v20.1.8 #24481
• {lang,toolchain}[lfbf/2025b,system/system] lfbf v2025b, SciPy-bundle v2025.07 #24482

---

Not as broadly tested as the OpenMPI variant. Test reports will hopefully come early next week...
