Sydney RunkleandClaude Opus 4.7 e5bfae0f9d test(add_messages): cover fast-path guards and format handling
Nine new tests pin the behavioral boundaries introduced by the
optimization: chunk / dict / tuple / missing-id left inputs must fall
through to full conversion, duplicate right ids and None right ids
must still be handled correctly, format="langchain-openai" and invalid
format must round-trip through the fast path, and the fast path must
return a fresh list rather than aliasing left.

Also picks up a ruff-format reflow in test_time_travel.py.
