pi-extension-types check is nondeterministic on the Linux runner: omp-channel smoke emits an extra state:active event

[schickling-assistant]

Symptom

checks.x86_64-linux.pi-extension-types failed on PR #447 run 33896046798 (head b5b0a22, which touches no hooks/ or pi-extension code):

AssertionError [ERR_ASSERTION]: Expected values to be strictly deep-equal:
+ actual - expected
  [
    {
+     state: 'active',
+     type: 'state'
+   },
+   {
      ask: 'question',
      blockedOn: 'human',
      reason: 'Which deployment target?',

Evidence it is not the PR

On the same head, nix build --rebuild .#checks.x86_64-linux.pi-extension-types re-executes the check locally and passes twice in a row (omp extension smoke: ok). The leading type:state,state:active event appears only under the runner's timing: the omp-channel smoke asserts a fixed event sequence that is order-sensitive.

Ask

Make the smoke robust to the state event (filter type:'state' before the deep-equal, or assert a subsequence), or make the channel deterministic in the fixture.
