buck2-change-detector - large-scale CI for Buck2 projects

[ndmitchell]

https://github.com/facebookincubator/buck2-change-detector/ - from the README:

For a Buck2 project, given which files have changed, figure out which targets have changed. This process is also known as target determination. The primary use case is for building a CI system.

If you want to build large scale CI on top of Buck2, I recommend using that project 😄
