* shellcheck
* fix(script): shellcheck and refactor
* fix(scripts): rename snake_casing no .sh
Follows Google's Shell Style Guide:
https://google.github.io/styleguide/shellguide.html
Script names must use snake_casing
Remove the `.sh` extension on `chmod +x` scripts because
the shell interpreter choice is in the shebang.
The `.sh` extension is to be maintained for sourced scripts because
those are not stand-alone executables:
```sh
. sourced_script.sh # . sourcing
source sourced_script.sh # alternate syntax
```
* decomp
* Stay CI
