Return empty body for empty/oversized range requests matching Go

Go's ProcessRangeRequest returns nil (empty body, 200 OK) when
parsed ranges are empty or combined range size exceeds total content
size. The Rust buffered path incorrectly returned the full file data
for both cases. The streaming path already handled this correctly.
