Previously, reserved table properties (except
format-version) were silently ignored when set viaUpdateProperties::Set(). This caused undetected configuration drift compared to Java, which throws exceptions for such attempts.Now attempts to set reserved properties accumulate a validation error via
ICEBERGER_BUILDER_CHECK, surfaced atApply()time. This matches Java's loud-failure behavior.
