Handle edge cases and errors gracefully:

1. SSH connection failures
   - Host unreachable
   - Authentication failures
   - Connection timeouts

2. Tmux issues
   - Tmux not installed
   - Socket permission issues
   - Window creation failures

3. Invalid input
   - Duplicate hostnames (README notes this needs handling)
   - Empty host list
   - Invalid host names (are all hostnames valid tmux window names?)

4. Resource cleanup
   - Clean up on SIGINT/SIGTERM
   - Clean up if main process crashes
   - Handle partial completion states

5. Informative error messages
   - Clear indication of which host failed
   - Suggestions for common issues
