fix: Handle Claude CLI unavailability gracefully in CI

- Add try-catch around pty.spawn() to prevent crashes when PTY unavailable
- Add unhandledRejection/uncaughtException handlers for graceful degradation
- Add checkBackendHealth/waitForBackendHealth utilities for tests
- Add data/.api-key and data/credentials.json to .gitignore
