// Multi-CLI bridge example.
//
// Demonstrates Squire's core differentiator: spawning multiple, different
// CLI agents from the same Node process and treating them as peers.
//
// Flow:
//   1. Claude Code answers the first prompt.
//   2. Its reply is captured and passed to Gemini CLI as context for a
//      follow-up prompt.
//   3. Gemini's reply is printed.
