Same fan-out as /search/sources, plus an LLM synthesis pass that produces a cited answer. Returns { answer, citations, results, sources_failed, cost } — structurally /search/sources plus answer and citations. When the synthesis model fails (timeout, malformed structured output), the endpoint still returns 200 with answer: null and the underlying sources intact (so callers get the dump rather than a hard failure). Charges sum of upstream provider costs + LLM token cost + $0.05 lava-search markup.

Synthesized answer with citations plus the underlying sources. When the LLM step fails, answer is null and cost.synthesis_error is set, but the rest of the payload is unchanged.
