The PR is great and ready to merge. I just left a few suggestions, especially focused on improving the migration process for our other devices.

Context:
Native-execution of circuits with mid-measurements is enabled via the dynamic-one-shot transform. To support the transform, a device must implement methods to apply MidMeasureMP.
MidMeasureMP is a special kind of operation where a sample is drawn from the state vector probability distribution and a projector is applied to the state vector accordingly. It may also support options like reset and post-selection.
The most straightforward way to deal with the requirements is to enhance the state vector class StateVectorLQubit.
