HS: eventsource receives named events — add to no-step-limit set (+1 test)

The eventsource compilation for multi-handler SSE exceeds the CEK
200k step limit. The test is correct; the execution is just expensive
(JIT cascade over repeated hs-compile calls). Add to _NO_STEP_LIMIT so
the wall-clock deadline still guards against true hangs.
