# =============================================================================
# StellarSettle – Interactive Testnet Setup & Multi-Contract Deploy CLI (#453)
# =============================================================================
#
# Wraps scripts/deploy.sh, scripts/package-wasm.sh, and scripts/smoke-test.sh
# behind a single entrypoint. With no arguments and a TTY, shows an interactive
# menu; otherwise dispatches to the requested subcommand.
#
# Usage:
#   bash scripts/cli.sh                 # interactive menu (TTY only)
#   bash scripts/cli.sh setup           # interactive testnet .env wizard
#   bash scripts/cli.sh build           # build release WASM (wasm32v1-none)
#   bash scripts/cli.sh package [dir]   # package WASM + checksums
#   bash scripts/cli.sh deploy [--dry-run]
#   bash scripts/cli.sh smoke           # run testnet smoke test
#   bash scripts/cli.sh status          # show current .env / contract IDs
# =============================================================================
