1//! Logic for opening a local session — a neutral helper shared by the interactive REPL
2//! (`repl`) and the single-shot (`oneshot`) paths.
3//!
4//! Both frontend paths execute files and commands directly on the local machine: fs and
5//! shell both use the local backend, and the frontend is marked [`Frontend::Cli`]. They
6//! depend on this module at the same level, not on each other — this avoids making
7//! oneshot depend on the repl module (which would tie oneshot to the `repl` feature).
