Subject: [PATCH] Add model token pricing types

Add token-level billing types to Node SDK types: add tokenPrices to ModelBilling and new interfaces ModelBillingTokenPrices and ModelBillingTokenPricesLongContext. Include fields for input/output/cache prices, batchSize, contextMax, and longContext tier. Provides structured metadata for model pricing and long-context tiers used by billing and UI logic.
