#   1. verifies gh auth
#   2. creates two PRIVATE GitHub data repos (Claude + OpenClaude)
#   3. writes ./.env with repo names + paths
#   4. invokes backup.sh once
#
# Usage:
#   ./setup.sh                                  # prompt for repo names
#   ./setup.sh claude-repo openclaude-repo      # names as args (no flag)
