test: change command to simple echo for debugging

Changed from 'claude --dangerously-skip-permissions\n' to 'echo "WebSocket test"\n'
to test if the WebSocket closure issue is related to the command itself.

This will help determine if:
1. The issue is with the command length/format
2. The issue is with WebSocket data transmission in general
3. The PTY is handling the command correctly
