Usage:
  setup.sh <repo_name_or_dir> [--mode <process|docker|cloudrun>] [--deploy|--uninstall] [--repo <git_url>] [--ref <git_ref>] [--dir <path>]

Examples:
  # Remote install (process mode):
  # curl -fsSL "https://raw.githubusercontent.com/cloud-neutral-toolkit/<repo>/main/scripts/setup.sh?$(date +%s)" | bash -s -- <repo> --mode process --deploy
  #
  # Remote install (docker mode):
  # curl -fsSL "https://raw.githubusercontent.com/cloud-neutral-toolkit/<repo>/main/scripts/setup.sh?$(date +%s)" | bash -s -- <repo> --mode docker --deploy
  #
  # Remote install (Cloud Run mode):
  # curl -fsSL "https://raw.githubusercontent.com/cloud-neutral-toolkit/<repo>/main/scripts/setup.sh?$(date +%s)" | bash -s -- <repo> --mode cloudrun
  #
  # Local:
  # bash scripts/setup.sh <repo> --mode process
  #
  # Uninstall:
  # bash scripts/setup.sh <repo> --mode process --uninstall

Notes:
  - Safe: no secrets written; no destructive actions.
  - If .env does not exist, it copies .env.example -> .env (placeholder only).
