`host.exec` rewrites exit value of spawned process to 1

[lemmy]

When executing a command such as:

host.exec('grep', ['"[\""', 'file.txt']);

If grep encounters a syntax error or similar issue, it exits with code 2. However, in nodehost.ts

genaiscript/packages/cli/src/nodehost.ts

Lines 614 to 626 in bc4456d

	if (!ignoreError) {
	trace?.error("exec failed", err)
	}
	return {
	stdout: "",
	stderr: errorMessage(err),
	exitCode: 1,
	failed: true,
	}
	} finally {
	trace?.endDetails()
	}
	}

, genaiscript catches the error and override the original exit code, returning 1 instead.

This behavior masks the real exit status of the executed process, making it impossible to distinguish between different failure modes—e.g., grep returning 1 for "no matches found" versus 2 for an error.

Expected Behavior

host.exec should preserve and propagate the actual exit code of the subprocess so that consumers can handle different exit codes correctly.
