fix(pricing): add October catalog display prices

 # Changelog
 
+## Unreleased
+
+- Add reviewed display pricing for the October catalog additions — `claude-sonnet-5-5`, `gpt-6.1-sol` (with its 272K long-context tier), `deepseek/deepseek-v4.1-flash-fast`, and the free `inclusionai/ling-3.1-flash:free`. Apply the DeepSeek V4 weekday peak-pricing window to `deepseek/deepseek-v4.1-flash-fast`. Models absent from `MODEL_COSTS` silently fall back to a zero display cost, so the snapshot now covers all 85 advertised models.
+
 ## 0.7.4 - 2026-10-05
 
 - Use the Provider API's OpenAI Responses wire (`/provider/v1/responses`) for models whose `/provider/v1/models` entry advertises `/responses`, keeping OpenAI Chat Completions for chat-only models and Anthropic Messages for Claude. The wire is resolved per model from `supported_endpoints`, falling back to Chat Completions when the catalog omits the field. This also enables prompt caching (`prompt_cache_key` is forwarded on `/responses` but ignored on `/chat/completions`): repeated prefixes bill at cache-read instead of full input price ([#132](https://github.com/patlux/pi-commandcode-provider/issues/132), [#133](https://github.com/patlux/pi-commandcode-provider/pull/133)).
