//! Entry-point for the `codex-exec` binary.
//!
//! When this CLI is invoked normally, it parses the standard `codex-exec` CLI
//! options and launches the non-interactive Codex agent. However, if it is
//! invoked with arg0 as `codex-linux-sandbox`, we instead treat the invocation
//! as a request to run the logic for the standalone `codex-linux-sandbox`
//! executable (i.e., parse any -s args and then run a *sandboxed* command under
//! Landlock + seccomp.
//!
//! This allows us to ship a completely separate set of functionality as part
//! of the `codex-exec` binary.
