Flaky: event-await-cli "parks, restarts, and replays two event wakes" exits 1 instead of parking after daemon restart #639
Description
packages/sdk/tests/event-await-cli.test.ts > "parks, restarts, and replays two event wakes through the actual CLI" fails intermittently in the linux-x64-artifact job.
Failure
After the daemon restart the CLI exits 1 where the probe expects a park (exit 4):
AssertionError [ERR_ASSERTION]: Expected values to be strictly equal:
1 !== 4

Where it is red / green on main (Relayflow v2 Cloud runtime artifact)
| commit | result |

7379ad7 (#633) changes only examples/babysitter/ and abf01b9 predates it, so this is not a regression from those merges.
Local reproduction attempt
Built relayflowd and the SDK at each commit, then RELAYFLOWD_BIN=<target>/debug/relayflowd npx vitest run tests/event-await-cli.test.ts five times each:
22cd1836 run 1-5: Tests 1 passed (1)
7379ad73 run 1-5: Tests 1 passed (1)
So it does not reproduce on an idle machine. The likely suspect is timing in the restart → second-wake path under CI load. The test's failure output includes each CLI invocation's stdout/stderr (the probe logs them), which should show what the post-restart flows call reported.
