//! Demonstrates `codex execpolicy check` via the wrapper.
//!
//! Note: not every Codex CLI release includes this command. When the binary is missing it,
//! this example prints a short skip message.
//!
//! Usage:
//! - `cargo run -p unified-agent-api-codex --example execpolicy_check`
//!
//! Environment:
//! - `CODEX_BINARY` (optional): path to the `codex` CLI binary (defaults to `codex` in PATH).
//! - `CODEX_HOME` (optional): Codex home directory for config/auth.
