fix(server): stop Claude resume handshakes from completing turns that never ran - #5710

💭 The imports are fine I'm weighing whether including the provider's error message in the log violates the convention against copying raw wire payloads. Since the code already emits raw payloads to events elsewhere and this is a diagnostic log rather than an error attribute, it seems acceptable to include. Now I'm checking the ProviderRuntimeIngestion.ts changes — the behavior modification has tests, which is good. The Effect service usage looks fine: Effect.runPromise in tests is acceptable, and Effect.forkChild is appropriate. The test harness dispatch function also uses Effect.runPromise correctly. I don't see any ManagedRuntime.make or service-instance parameters being added, just the two production edits and tests. The log uses Effect.logInfo with an object argument, which is correct for Effect v4. Since backend behavior is changing, the focused tests satisfy that convention requirement.
