List catalog models: current basket members plus retired ex-members

Current basket members carry inBasket=true with manifest-attested prices. Models that were representatives in a past confirmed revision but left the basket stay listed with inBasket=false and retiredAtRevision set; their prices come from the live catalog (ModelPrice). Soft-deleted models and retired models without any catalog price are not listed. Prices here are what providers charge: usdPricePerMillion and the cache and reasoning blocks carry no routing markup, and markedUpUsdPricePerMillion carries it. For prices as billed, use /v1/oracle/pricing. Only the cache and reasoning components carry a provenance mark here, because only they are read from the live catalog. The input/output pair is the manifest-attested figure for a basket member (inBasket=true) and the live-catalog figure for a retired ex-member, and this endpoint publishes it unmarked in both cases. For the catalog's own mark on a model's input and output, use /v1/oracle/catalog or /v1/oracle/resolve. Models are identified by the canonical vendor-prefixed id (openai/gpt-5.5).
