* fix: all 'devel' builds should be considered 'dev' builds.
If CI needs to be distinguished from a dev build, we should add
a different pre-release tag for those builds.
* change CI version checking to be more strict
* chore: add /v2 to import module path
go mod requires semantic versioning with versions greater than 1.x
This was a mechanical update by running:
```
go install github.com/marwan-at-work/mod/cmd/mod@latest
mod upgrade
```
Migrate generated files to import /v2
* Fix gen
* Add endpoint for getting build info
* Add build info XService
* Add version with link to page footer
Partially addresses #376.
* Lift buildinfo package
