* feat(providers): add Kie provider for Claude, GPT, Grok, and Kimi models

* improvement(providers): use the official Kie logo and list Kie as a streaming tool-call provider

* fix(providers): keep Kie retry headers on rewritten errors and cover the request contract

* fix(providers): parse untyped Kie JSON responses and match content types case-insensitively
