This uses a new feature from snapbox that let's us render terminal
styling in SVG files. This let's us see / visualize ANSI escape codes,
including in github's UI (will render images, including side-by-side
images for diffs).
This just gets rid of irrelevant packages in the registry. Looking into
which versions aren't needed would require a deeper pass, so I held off
on that for now.
Before, the tests were in the 300-500ms range and now they take
100-300ms.
This did call to my attention that `unrelated` is misspelled as
`unrelateed` but holding off on fixing that to reduce conflicts.
This is done in the command, rather than in the op,
- To consistently construct the `Workspace`
- It is more composable as an API
A downside is we update the git dependencies a second time.
We are not rolling back on error.
- For some errors, the user might want to debug what went wrong
- Rollback adds its own complications and risks, including since its
non-atomic
Fixes#10901
