/**
* chatCore wire target-format resolver (Quality Gate v2 / Fase 9 — chatCore god-file
* decomposition, #3501).
*
* Pure resolution of the provider alias + the upstream target format used to translate the request:
* apiFormat==="responses" forces OpenAI Responses; otherwise the model's registry target format, then
* the per-model custom override (#2905), then the provider default. Returns both `alias` (reused by
* the handler when stripping the `alias/` prefix off the upstream model id) and `targetFormat`.
* Side-effect-free; byte-identical to the previous inline block. Sits alongside the other
* request-setup resolvers (resolveChatCoreRequestSetup / resolveChatCoreRequestFormat).
