hellogrok-cli 0.1.32 aflaai

Changed
- Removed the implicit supports_backend_search = true default for models on the exact first-party api.deepseek.com endpoint. DeepSeek has retired its hosted web search — the current Responses API documents web_search and all other built-in tools as ignored — so the old default routed web_search to a channel that silently answers without search results, bypassing the client-search fallback chain ([models].web_search, GROK_WEB_SEARCH_MODEL, authenticated official fallback) with no error or sources. An omitted field now preserves Grok Build catalog behavior for every provider uniformly; explicit true/false values keep their meaning, and a channel explicitly set to true still works for relayed endpoints that implement a real search extension. DeepSeek-specific protocol handling (the [1m] Messages alias, thinking normalization, 660-second idle policy, and the Chat Responses bridge dialect) is unchanged.
