Detailed Description

Doctest-based unit tests for DNDS Serializer classes.

Covers SerializerJSON (per-rank, no MPI needed for logic) and SerializerH5 (parallel HDF5, requires MPI). The JSON tests verify scalar, vector, uint8 (with/without codec), path operations, and shared-pointer deduplication. The H5 tests verify scalar, vector, distributed vector (non-uniform per-rank sizes), uint8 (two-pass read), path operations, and string round-trips.

Note
H5 parallel I/O requires all MPI ranks to open the same file. The TmpH5() helper broadcasts rank 0's PID so that the filename is identical across all ranks. FileGuard uses shared=true for H5 files so only rank 0 deletes the file, followed by an MPI_Barrier.

Build: cmake --build . -t dnds_test_serializer -j8 Run: mpirun -np 1 ./dnds_test_serializer (JSON + H5 single rank) mpirun -np 4 ./dnds_test_serializer (H5 distributed tests)
