feat(core): add provider-to-pi-ai adapter, replace inline piProvider resolution

- 新增 packages/core/src/llm/providers/provider-to-pi-ai.ts 提供 resolvePiAiProvider(endpoint)
- 显式映射表：zhipu → zai（pi-ai 识别不到 open.bigmodel.cn）,
  openrouter → openrouter, githubCopilot → githubCopilot
- anthropic-messages 协议统一映射到 anthropic；其余默认 openai（pi-ai 再按 baseUrl 嗅探）
- createLLMClient 里 piModel.provider 字段改调 resolvePiAiProvider
- 其他 Provider/getProvider refs 批量 rename 到 Endpoint/getEndpoint（补齐 R1-2 遗漏）

R1-3，测试 831 全绿。
