# Official release preparation script (pre-PR)
#
# Automates steps 1-8 of the official release process:
#   1. Log out of npm
#   2. Checkout main
#   3. Pull latest from upstream
#   4. Create a timestamped release branch
#   5. Build the release CLI
#   6. Run the release dry-run (interactive)
#   7. (User confirms in the interactive CLI)
#   8. Push the branch to origin and open a PR
#
# Usage: yarn release:prep
