feat(ai): Agent SSE + Anthropic/responses tools + P1 确认写

- Agent 支持 SSE（步骤边推、正文分块），JSON 非流式 fallback
- tool calling 覆盖 openai-chat / anthropic / responses（单测解析回灌）
- P1：mcp.json mode=read_write 才可写；需 confirm_danger；Agent 剥离模型自带令牌
- GET /api/ai/mcp-status、POST /api/ai/agent/confirm；审计 source=mcp|agent
