c6e4d4ab71 Add OpenMP parallelization to BSSN RHS hot-path stencil routines 
Enable OpenMP threading for the dominant computational kernels:
- makefile.inc: add -qopenmp to f90appflags
- diff_new.f90: split fderivs/fdderivs into OpenMP interior + serial boundary
- kodiss.f90: split kodis into OpenMP interior + serial boundary
- lopsidediff.f90: add OMP PARALLEL DO COLLAPSE(2) to lopsided
- fmisc.f90: parallelize symmetry_bd bulk array copy
- bssn_rhs.f90: add OMP WORKSHARE to array-syntax operations

24bfa44911 Disable NaN sanity check in bssn_rhs.f90 for production builds 
Wrap the NaN sanity check (21 sum() full-array traversals per RHS call)
with #ifdef DEBUG so it is compiled out in production builds.

This eliminates 84 redundant full-array scans per timestep (21 per RHS
call × 4 RK4 substages) that serve no purpose when input data is valid.

Usage:
  - Production build (default): NaN check is disabled, no changes needed.
  - Debug build: add -DDEBUG to f90appflags in makefile.inc, e.g.
      f90appflags = -O3 ... -DDEBUG -fpp ...
    to re-enable the NaN sanity check.
