Rainbow Gum logging module #4021

@jknack I have a logging framework I think I showed you in the past but was not ready or Jooby was not ready because it did not target 21. I have put an enormous amount of effort (it is not vibe coded but now is assisted) on making Rainbow Gum the future of logging. This includes Scoped Values, Open Telemetry, Graal VM native checking on every build, JFR support etc.

I can either add the support directly in Rainbow Gum's project like I have for Helidon, Micronaut, and Spring Boot or if you like a module directly on Jooby.

I think you might like Rainbow Gum's choices and given this project often favors performance is a good fit.

An interesting thing is that Rainbow Gum can use Typesafe config application.conf directly or the Environment class (I can't recall which class you have in Jooby that has properties but I think its Environment).

Logging btw does indeed impact performance based on my benchmarking but you can easily test these days with an LLM.
