nemo-repo-core dropped from 1.0.0 to 0.1.0 while its API is still
unsettled, and requireCore treats the minor as the breaking component in
the 0.x range.
Open Terminal Here and Open in Editor were bundled with git emblems, columns and a properties tab, but neither of them has anything to do with git and both work on any folder. They are their own plugin now, on the nemo-repo-core config and launcher layer.
The editor entry used to be shown only when Visual Studio Code was installed, whatever editor_command said; it now checks the configured command. The terminal entry is hidden when no emulator is present instead of appearing and doing nothing.
