Resilience Suite flakiness at fixture startup

The Resilience Suite job in the pulsar workflow intermittently fails at fixture setup with:
```
TimeoutError: Pulsar did not bind consumers within 60.0s
test/resilience/harness/pulsar_control.py:199
```

The bind-wait helper in `harness/pulsar_control.py` documents this path as racy: "Polling the broker for a non-zero consumer count is racy after a kill+restart cycle: the old consumer count can linger." The 60s wait at pulsar_control.py:199 is the hard cutoff that trips.

Start in test/resilience/harness/pulsar_control.py at the bind-wait helper and the 60-second cutoff on line 199. Run the Pulsar workflow's Resilience Suite to reproduce the fixture-startup failure, then verify that the bind step completes reliably after a kill-and-restart cycle without the reported timeout.
