Restore cek_run IO hooks and cek_step_loop error handling lost by bootstrap

Browse Source 
bootstrap.py regenerated cek_run as a simple "raise if suspended" without
the _cek_io_resolver and _cek_io_suspend_hook checks. Also lost the
CekPerformRequest catch in cek_step_loop and step_limit checks.

This was the direct cause of "IO suspension in non-IO context" when island
click handlers called perform (via hs-wait). The CEK had no way to propagate
the suspension to the VM/JS boundary.
