Function run_native_commit 

pub fn run_native_commit(
    context: &GitContext,
    cwd: &Path,
    request: &PreparationRequest<'_>,
) -> Result<i32, PreparationError>

What: Runs native git commit in the shadow with the terminal attached and returns its exit code. Why: The editor and hook output reach the user unchanged, so the child inherits standard streams.

In TS you’d write (pseudocode):

await runTransactionGit({ gitPath, cwd, args, indexPath, unsetEnvironment, stdio: 'inherit', allowFailure: true });
