includes:
- easier repo declaration for playwright tests by @Gusted
- full backend build for pushing Git repos by @Gusted
- playwright testing (which fails with the current diff algorithm, but
passes with the new)
- disable eslint rule for conditional expect, because it defeats the
purpose (working around it would result in much more complex test code
in our cases)
