Add characters[i].stepfunVoiceId to all 106 prebaked homepage first-act
JSONs (firstact/ + firstact-portrait/) so cards produce sound when the
server runs StepFun. Generated by scripts/enrich-firstacts-stepfun.mjs —
one TEXT-provider LLM call per character picking from the 32-preset
catalog. voice (Xiaomi reference audio), imageUrl, and scene are untouched;
only the new stepfunVoiceId field is appended.
All 147 characters across both orientation sets are enriched (0 failures).
