fix: Dockerfile to include .env

## Summary

* fixed missing error handler in main
* add injectable build string in main
* add (dynamically linked) docker build
* add github CI workflow
* add extra but useful dev files in dev folder

* closes #93

## Notes

* We'll move to a self-hosted CI runner once it is installed on Gitea.
