feature: Dynamically enabling Dbux

[Domiii]

Especially, when using a bundler or, genrally, a build pipeline, enabling/disabling Dbux can be a pain.

• → When its not needed, running things with Dbux can slow down certain development tasks considerably.
• → Dev should be able to easily toggle Dbux on only when needed, then turn it off again.

TODO

• Make it easier to toggle Dbux.
  • Maybe dynamically re-load config?
  • Maybe provide an easy way to build two versions in parallel, with dynamic prioritization?
    • E.g.: frontend application is built twice; once with and once without Dbux. Runs on two different ports.
