Finish one conversion: a nonzero start records the converted offset
(read before the source was consumed) as the earliest reusable prefix, then
the new storage is materialized and the allocator pool released before
anything else converts, which bounds the live bf16 source plus quantized
copy to one layer. Returns converted.
