Introduce inert OGG_COUNTED_BY*_ macros and annotate ogg_stream_state.body_data with OGG_COUNTED_BY_OR_NULL(body_storage). Keep capacity-then-pointer assignment and pointer-null-then-size-0 clear order so a future -fbounds-safety build can enforce the existing size relationship. Default builds are unchanged (macros empty; OGG_ENABLE_FBOUNDS_SAFETY=OFF).
