feat(zhipu): switch to anthropic-messages endpoint and split embedding provider

- zhipu (chat/reasoning/vision): baseUrl -> /api/anthropic, apiFormat -> anthropic-messages
  启用 Anthropic 协议的 thinking 字段以支持 GLM 深度思考流式输出
- zhipu-embedding (new): 独立承载 embedding-3, 保留 /api/paas/v4 + openai-completions
  Anthropic 协议不提供 /embeddings 端点
- zhipu-coding (Coding Plan): baseUrl -> /api/anthropic, apiFormat -> anthropic-messages
  与非套餐端点共用同一协议, 计费维度由 API Key 区分
- bump presetDataVersion 17 -> 18
