问题根因

staging 环境 flag 100% 不生效的根本原因：

1. WorkerSettings 类里没有 redis_url 字段，导致环境变量 REDIS_URL 完全没被 pydantic 读取
2. RenderEngineResolver 初始化时 getattr(settings, redis_url, None) 返回 None
3. fallback 到 broker_url，默认值是 redis://redis:6379/0
4. staging 的 redis 服务名是 xiaoxia-redis-staging，连接失败
5. Resolver 降级到 InMemory 实现，flag 永远是默认关闭状态
6. 所以 percentage=100 也永远返回 legacy 引擎

修复

在 WorkerSettings 中添加 redis_url 字段，让 REDIS_URL 环境变量正确映射。

影响范围

• 灰度发布 flag 不生效的 P0 阻断
• 只有一行代码变更，无风险

fix: add redis_url field to WorkerSettings to pick up REDIS_URL env var ... 2fbdb8f992

Root cause of flag not working in staging:
- WorkerSettings had no 'redis_url' field, so REDIS_URL env var was ignored
- RenderEngineResolver fallback to broker_url (default redis://redis:6379/0)
- Staging redis hostname is xiaoxia-redis-staging, so connection failed
- Resolver degraded to in-memory store, flag always defaulted to disabled (legacy)

Fix: add redis_url field so REDIS_URL env var is properly mapped
