feat: Major Updates

- removed support for `projects` as the feature was very incomplete and it served little purpose
- added support for common settings between jobs using `~~shared-settings` as a key in the config
- cleaned up some items that have long bugged me
  - better reuse of code
  - better variable naming
  - improved flow and readability
  - formatting to the logs
