- deploy-prod (master → ubuntu-prod): Only deploys prod and public stacks
- deploy-dev (dev → ubuntu-dev): Only deploys dev-only stacks
- Skips stacks without stack-type labels (with warning)
- Fixed: Only create .env from template if .env doesn't exist
This prevents dev-only experimental stacks from being deployed to
production, even if they're in the master branch.
