- 真实基线：SimilarAsinImageEmbedder(OkHttp) connect/read=imageDownloadTimeoutSeconds(5s)、call=2×download(10s)、prefetch 1800s - resolver 提供 connect/read/call/prefetch/maxRetries 访问面，模块级优先、命名空间兜底，不改调用点 - 仅新增类与测试，零生产行为变化

|
||
*
|
||
* 现网真实基线（已核实，对应 task-166 契约表"图片下载"行）：
|
||
* - SimilarAsinImageEmbedder 用自建 OkHttpClient（非共享 JDK 池）：connect/read/write =
|
||
* aiimage.similar-asin.image-download-timeout-seconds（默认 5s），call = 2×download（10s）；
|
||
* - 整批预取预算 aiimage.similar-asin.image-prefetch-timeout-seconds（默认 1800s）；
|
||
* - 无显式次数重试（依赖 OkHttp retryOnConnectionFailure + 上游批次重提），图片缓存幂等。
|
||
*
|
||
* resolver 语义：模块级现有配置优先（保证接入切点行为不变），命名空间 aiimage.http-client.*
|
||
* 兜底；不改动 SimilarAsinImageEmbedder 调用点，仅提供稳定访问面。
