/**
 * Provider 请求形态测试矩阵（v0.6.4 P2-6）
 *
 * 此前 ollama（599 行）/ anthropic（532 行）两个最复杂的适配器零测试 —— 恰好也是
 * 本轮审计中缺陷密度最高的文件。本文件通过 mock fetch 记录真实请求体，
 * 锁定以下契约：
 *
 * Anthropic:
 *  A1 消息转换（system 顶层 / user-assistant-tool 三角色映射 / 孤立 tool_result 过滤）
 *  A2 max_tokens 按模型钳制（引擎默认 63488 → sonnet 64000 / opus 32000）
 *  A3 thinking 预算下限保护（小 maxTokens 场景 budget≥1024 且 < max_tokens，此前 API 400）
 *  A4 thinking 开启时不传 temperature；关闭时显式传递
 *
 * Ollama:
 *  O1 options 映射（num_predict=numTokens、num_ctx=contextLength、stop、top_p）
 *  O2 think 参数 effort 映射（low→"low"、xhigh→"xhigh"、max/true→true）与未配置时缺省
 *  O3 图片归一化（data URI 剥前缀；无 URL 触发下载分支时零网络请求）
 *
 * Agnes:
 *  G1 思考模式对称性 —— thinkingEnabled=false 必须显式发送 enable_thinking:false
