/// When disabled, `GetObject` bypasses the chunk-streaming fast path entirely and
/// always uses the legacy reader path. This provides an operational stopgap for
/// regressions in the streaming data plane while keeping zero-copy internals
/// configurable independently for future opt-in validation.
