/**
 * Automated Soroban contract deployment script.
 *
 * Deploys the vault-registry, access-lease, and subscription contracts to a
 * Soroban network, initializes each with the admin key, writes the resulting
 * contract IDs to contract-ids.env, and verifies each contract on-chain.
 *
 * Usage:
 *   node scripts/deploy-contracts.cjs [--network testnet|mainnet] [--wasm-dir <dir>] [--yes] [--dry-run]
 *
 * Required environment variables:
 *   STELLAR_SECRET_KEY  - Secret key of the deploying account.
 *   NETWORK             - Target network (testnet|mainnet). Overridden by --network.
 *
 * Optional environment variables:
 *   SOROBAN_RPC_URL     - Soroban RPC endpoint (defaults to the public testnet
 *                         RPC for testnet; required for mainnet).
 *   CONTRACTS_WASM_DIR  - Directory containing the built *.wasm files. Overridden
 *                         by --wasm-dir. Defaults to ./target/wasm32-unknown-unknown/release.
 *   ADMIN_PUBLIC_KEY    - Address passed to each contract's init(admin). Defaults
 *                         to the deployer's public key.
