- scripts/test-targeted-xunit.ps1: replace @(x).Count checks with
[bool] coercion in Assert-FilterShape; StrictMode 'Latest' rejects
.Count on null even when wrapped in @().
- ConcelierInfrastructureRegistrationTests.AddConcelierPostgresStorage_
RegistersDurableObservationAndAffectedSymbolServices: wrap provider

IAsyncDisposable only, so sync Dispose at `using` scope end throws.
Follow-up to SPRINT_20260419_027/028.
