Description

Issue Description

Type: feature request

Describe what happened (or what feature you want)

gateway flow limit by error code instead of Throwable exception

对于 API gateway 目前不支持针对 4xx、5xx 等状态码记为错误（仅针对抛出异常记录错误）。希望可以针对 5xx 等状态码也记录为错误，这样就可以进行异常熔断降级了。

Research direction
Investigate the Sentinel gateway module, specifically the CircuitBreaker and GatewayFlowRule classes, to understand current error recording logic (only for Throwable exceptions). Consider how to intercept HTTP responses and treat 4xx/5xx status codes as errors for circuit breaking. Review the existing issue comments for design suggestions, particularly around configuration options and maintainer feedback.
