/**
 * CLI Abort Handler (BZ-667)
 *
 * Bridges SIGINT (Ctrl+C) to an AbortController for graceful stream cancellation.
 * First Ctrl+C aborts the stream and shows "Stream cancelled."
 * Second Ctrl+C within 1 second force-exits the process.
 *
 * Uses `prependListener` so the stream handler fires BEFORE the top-level
 * SIGINT handler in cli/index.ts (which calls process.exit). The listener
 * remains registered until `cleanup()` removes it. On the first Ctrl+C the
 * stream is cancelled gracefully; only a rapid second press exits.
 *
