* when `v` has no nulls (caller should gate on `v->attrs & RAY_ATTR_HAS_NULLS`
* before calling for the cheap fast-path).
*
* On return:
* *bit_offset_out (if non-NULL): bit-offset within the returned buffer
* that corresponds to v's row 0. Non-zero only for slices.
* *len_bits_out (if non-NULL): total bits addressable in the buffer.
* For inline, this is 128. For external, it's the ext->len * 8.
*
* The returned pointer is valid as long as `v` (and its ext_nullmap /
* attached index ray_t, if any) are not released or mutated. */
