v2.18.1

The last place /cost still priced plan usage: the prompt-caching savings line quoted dollars for subscription providers that bill a flat fee.

Added

• npm run export:catalogue writes the shipped model catalogue to
  Codeep-web/src/data/catalogue.json straight from PROVIDERS and the
  context/pricing tables, so codeep.dev renders what the client actually
  offers instead of a hand-kept list that had drifted to 4 models against a
  catalogue of 72.

Fixed

• Prompt-caching "savings" no longer invents money on a plan. /cost
  priced cached tokens at the provider's pay-per-use input rate even on Z.AI's
  Coding Plan, MiniMax, Kimi and Qwen — where caching saves latency, not money,
  because nothing is billed per token. The cache read/write counts stay (they
  are measured); the dollar figure now covers pay-per-use models only and says
  so when a session mixes both, and a plan-only session reads "caching saves
  latency, not money" instead. The billed at 0.1× / 1.25× input rate notes are
  likewise dropped where no per-token billing applies.
