Compaction writes the output budget into agent.options.maxOutputTokens.
LLMRequestPrep.prepare merges agent.options into providerOptions, and the
AI SDK serializes it verbatim into the request body; strict
OpenAI-compatible upstreams reject it with
'Unsupported parameter(s): maxOutputTokens'.
Strip the injection site. The cap is still enforced through two
independent paths: the constrained model passed downstream and the
llm.ts re-cap on prepared.params.maxOutputTokens.
