chore: add skippable setup to deploy script

[horsefacts]

Motivation

Deploy scripts should be idempotent: if we detect that contracts are already deployed, we should skip the post-deploy setup step.

Change Summary

Update deploy script to skip setup if contracts haven't changed. Add default values to .env.example.
