Function is_expected_provider_registration 

pub fn is_expected_provider_registration(
    provider: &CapabilityProvider,
    before: &ProviderRegistrationSnapshot,
    expected_provider_id: &str,
) -> bool

True when this is a fresh registration for the exact deployment instance.

Other providers may register concurrently while a package is starting. They are unrelated and must never receive this instance’s lifecycle config.
