[feature]考虑增强熔断恢复策略

## Issue Description

Type: *bug report* or *feature request*

### Describe what happened (or what feature you want)

目前看熔断恢复策略仅仅判断当前请求是否达到阈值，是否考虑增强熔断恢复机制
比如引入预热恢复或者其它算法机制，这样能够减少错误恢复带来的影响
### Describe what you expected to happen

Start by reviewing Sentinel's existing circuit-breaker recovery implementation and the current-request threshold logic. Clarify whether warm-up recovery or another algorithm is wanted, then define measurable recovery behavior and its impact before identifying the affected Java code and tests.
