Shows applied dnf transactions newest-first, flagging the current
state and the original release, each expandable into dnf history
info. Opens as a separate OS process/window via --history rather than
a page in the main app. run.sh builds and runs through a toolbox since
the host's build toolchain (cmake/ninja/gtk3-devel) isn't available
directly on this immutable OS.
