Use the dict _capture_settlement() returns instead of re-reading self._last_settlement, which a concurrent call on a shared client could overwrite — making the per-call settlement field as race-free as cost_usd.
Pre-existing formatting drift that fails CI's black --check; unrelated to the cost change but blocks this PR's pipeline.

Streaming analogue of ChatResponse.cost_usd: _iter_and_archive / _aiter_and_archive (Base + Solana) now set chunk.cost_usd = cost_usd on every paid-path chunk. It rides on the per-call chunk object, so it is race-free under shared-client concurrency, unlike client._last_call_cost. Free / 200-first streams skip the signer and carry no cost_usd. Lets blockrun-litellm report the real wallet deduction on streamed calls instead of a token×list-price estimate (blockrun-litellm #12).

_handle_payment_and_retry(sync + async) now attachessettlementfrom the dict_capture_settlement()returns instead of re-readingself._last_settlement. A concurrent call on a shared client could overwrite that shared field between capture and read; using the return value makes the per-callsettlementas race-free ascost_usdalready is.
