chore(git): adding pre-commit hooks

Git hook scripts are useful for identifying simple
issues before submission to code review.
We run our hooks on every commit to automatically
point out issues in code such as missing semicolons,
trailing whitespace, and debug statements.
By pointing these issues out before code review,
this allows a code reviewer to focus on the architecture
of a change while not wasting time with trivial style nitpicks.
