erio	bf0bbe0be7	feat(gateway): raise upstream response read limit 8MB -> 128MB (configurable) ... 图片生成 API 返回的 base64 内联图响应经常超过 8MB 单次读取上限，被 ReadUpstreamResponseBody 拦截成 502 upstream_error。 单张 4K PNG base64 最坏约 67MB，多张候选图或 imageSize=4K 的 image_generation 一次请求能轻松到 30MB+。把默认上限提到 128MB 能覆盖 2-3 张 4K 图，相对 请求体上限 256MB 仍有缓冲；同时抽出 config.DefaultUpstreamResponseReadMaxBytes 共享常量，viper 默认值和 service 层兜底共用，消除两处同步魔法数字。 仍可通过 gateway.upstream_response_read_max_bytes 配置项覆盖。	2026-04-17 22:07:15 +08:00
erio	10699eeb34	refactor: extract ReadUpstreamResponseBody to deduplicate upstream response read + too-large error handling ... Consolidates 9 call sites of resolveUpstreamResponseReadLimit + readUpstreamResponseBodyLimited + ErrUpstreamResponseBodyTooLarge error handling into a single ReadUpstreamResponseBody function with TooLargeWriter callback for API-format-specific error responses (Anthropic, OpenAI, countTokens).	2026-04-16 01:53:22 +08:00
