"""Run with each SDK/runtime pair in a fresh MSB_HOME and an explicitly selected runtime.

Set MSB_PATH and MSB_LIBKRUNFW_PATH to a matching runtime/firmware pair, then run
this file with the old SDK Python environment and again with the current SDK.
The homes must be isolated: this checks launching, not database downgrades.
