Segundo incremento da decomposição do chatCore.ts (5127 LOC). Extrai a primeira fatia PURA da fase de request-setup do handleChatCore: a metadata de roteamento de modelo (apiFormat + targetFormat via structural-narrowing sem 'as any', + o requestedModel com fallback) — para um leaf testável em chatCore/requestSetup.ts. - resolveChatCoreRequestSetup(modelInfo, body, model): ChatCoreRequestSetup — puro, byte-idêntico ao bloco inline. Tipo ChatCoreRequestSetup é a semente do futuro ChatCoreContext (as fases maiores — setup/dispatch/streaming — virão depois). - chatCore.ts: bloco inline (~21 ln) vira 5 linhas. - 5 testes de caracterização (narrowing + fallback do requestedModel). 185/185 chatcore tests (caracterização do handleChatCore preservada), typecheck 0, complexity OK 1896 (mudança neutra), file-size encolhe. Timing: feito como leaf PURO seguro porque a v3.8.30 está finalizando — o ChatCoreContext mutável (carrega body + 20 inputs no hot-path) cabe melhor em v3.8.31. Follow-up: atribuir requestSetup.ts a um batch de mutação no nightly (como os demais chatCore leaves); 5 testes cobrem as branches por ora.
