mohdel v0.114.0

Added

• Anthropic per-TTL cache-creation accounting. The streaming adapter now reads
  usage.cache_creation.ephemeral_1h_input_tokens and exposes
  cacheWrite1hInputTokens on the done result. computeCost prices the 1h write
  tier via a new optional spec field cacheWrite1hPrice; the 5m portion
  (cacheWriteInputTokens − cacheWrite1hInputTokens) stays on cacheWritePrice.
  A request may mix TTLs, so both tiers can be non-zero.
• Gemini implicit-cache read accounting. The adapter now reads
  usageMetadata.cachedContentTokenCount and exposes cacheReadInputTokens on
  the done result, priced via the existing cacheReadPrice spec field.

Fixed

• Gemini cached input was billed at full inputPrice. Cached tokens are now
  subtracted from inputTokens (subset convention, matching the OpenAI adapter)
  and priced at cacheReadPrice, so reported cost reflects the provider's
  cached-token discount.
• Anthropic 1h cache writes were priced at the 5m rate. They now bill at
  cacheWrite1hPrice when the spec provides it.

Notes

• Additive and backward-compatible. When cacheWrite1hInputTokens is absent or a
  spec omits cacheWrite1hPrice, the whole write bills at cacheWritePrice —
  prior behaviour. Realizing the corrected rates requires catalog specs to carry
  cacheWrite1hPrice (Anthropic) and cacheReadPrice (Gemini); without them the
  new fields are observability-only and cost is unchanged.
