chore: fix the double compiling of lib and bin (#1616)

* fix: rust modules are compiled twice

The modules being declared both in the _library_ crate and the _binary_
crate made cargo compile everything twice:

1. for the library
2. for the binary

What happened was:

1. The library "starship" was compiled.
2. The binary "starship" (and all its modules) were compiled.

* fix: stop compiling every rust module twice

restrict visibility

* Run cargo fmt

* Add bug_report module
