//! `solana-program-test` backend — interface defined, implementation pending.
//!
//! The type and its construction surface exist so callers can target it today;
//! [`ExecutionBackend::run`] returns [`crate::Error::BackendUnimplemented`]
//! until the `program-test` integration is wired up. Keeping the Solana
//! dependency out of the default build keeps the core pure Rust and fast to
//! compile.
