Module command_runner 

Injectable subprocess execution for hooks, filters, credentials, and helpers.

All std::process::Command usage in non-test library code lives in SystemCommandRunner. Embedders and tests use RecordingRunner or custom CommandRunner implementations.

Library guide: command_runner

use grit_lib::repo::{InitOptions, Repository};
let dir = tempfile::tempdir()?;
let _repo = Repository::init(dir.path(), &InitOptions::default())?;
