* Clean up axum-debug crate
Mostly just brings the crate more in line with the rest of the crates in
the workspace.
I've also removed the axum-debug-macros crate since axum-debug only
contained one re-export from axum-debug-macros. So we didn't need two
crates. Can always bring the "backend" crate back if we need things in
axum-debug that aren't proc-macros.
* Just testing: This should make CI fail
* Misc CI clean up
* fix intentional breakage
* fix changelog
* Remove rustfmt config for now as it gives warnings on stable
* Fix paths
