Builds a kDepthR32F frame from metric-depth floats (row-major), as DepthPipelineSource emits.

Helper: build a struct with three float64 fields (x, y, z)

Serializes a depth-encoded sdk::Image (the type the depth source consumes — there is no kDepthImage producer).

Tell the session which dataset is the active live stream (0 = none). While set AND playback is playing, recomputeRange() scopes the playback range to
