Function addDataset

pj_runtime/tests/session_manager_test.cpp:401–411

Creates a dataset on its OWN TimeDomain (mirroring FileLoader's one-domain-per- source) and writes scalar samples. The per-source domain is required because "align starts" / Timeline offsets are written to the domain — a default (id 0) domain carries no shiftable offset.

// "align starts" / Timeline offsets are written to the domain — a default (id 0)
// domain carries no shiftable offset.
