Subject: [PATCH] todo(15): in-progress

build_masked_example normalises apply_chat_template's BatchEncoding (transformers 5.x) and list[int] (4.x) returns via a _render_ids helper; a BatchEncoding-returning fake tokenizer produces the same mask as the list-returning one (regression test added); existing tests pass; mypy strict clean; verified end-to-end on the box that sekft-train --inspect produces a correct assistant-only mask against Mistral.
