This header provides the OpenMP threading infrastructure for :ref:`namespace_OpenThermo`:

- Physical CPU core detection (Linux, macOS, Windows)

- HPC job scheduler CPU allocation detection (SLURM, PBS, SGE, LSF)

- Thread count validation and clamping with user-friendly notifications

- Automatic parallelization strategy selection (outer T/P scan vs inner vibrational loop) based on workload characteristics

- OpenMP runtime configuration with nested parallelism control



All functions are header-only (inline) to avoid link-time overhead. When OpenMP is not available, stub functions are provided so the rest of the codebase compiles and runs single-threaded without #ifdef guards.
