// CLI headless use cases  (cline -y / cline --json / piped stdin)
//
// These tests run cline as a child process (no TUI harness) and assert on
// stdout, stderr, and exit codes.
//
// Tests tagged @live require a configured provider and are skipped by default.
// Run them with:  CLINE_BIN=... npm test -- headless @live
