feat: guarantee codegen targets are executed on pre-commit

[floreks]

• Updated README to describe how to enable git hooks for this repo
• Added make install-git-hooks root target that updates local git core.hooksPath for this repo to point to the custom hooks dir
• Added custom pre-commit script that checks for staged files path and if controller or client files were updated, it will run dedicated codegen targets.

$ git commit -m "initial commit"
