A non-existent output.directory previously surfaced only as a cryptic HDF5 crash. Add OutputParameters::validate(), called from Parameters::readInput on first rank only, which throws std::invalid_argument with a clear message naming the missing directory. Validation is kept separate from OutputParameters::readWrite so the parsing path stays disk-free and unit-testable; this also avoids needing the existing ReadAll fixture to point at a real path. Follow-up PRs for bugs #2–#4 are expected to add validate() to other parameter sections under the same convention.

Speaking with @gbalduzz further on this he thinks we should decide what changes we need to put this in without a runtime switch since it greatly reduces how difficult to understand CUDA failures are.
