//! Contract Deployment Engine (ENG-13).
//!
//! Orchestrates `UploadContractWasm` → `InstantiateContract` → poll settlement,
//! reuses `sdkt-wasm` metadata, `sdkt-xdr` XDR helpers,
//! and `sdkt-rpc` submission/polling engine. No duplicate tx logic.
//!
//! Cache lookup is performed by the CLI (consumer of both sdkt-rpc and sdkt-storage)
//! to avoid cyclic dependency: sdkt-storage --> sdkt-rpc exists, so sdkt-rpc cannot
//! depend on sdkt-storage.
