Copilot adc90b4d2d Apply rate limiting before singleflight to prevent goroutine blocking on etcd timeout (#2841 )

* Initial plan

* Apply rate limiting before singleflight to prevent blocking

- Check rate limiting BEFORE entering singleflight
- If rate-limited AND stale cache exists, return stale cache immediately
- This prevents all goroutines from blocking when etcd is down/slow
- Maintains stampede prevention via singleflight for non-rate-limited requests
- All existing tests pass

* Fix variable shadowing in rate limiting check

- Rename shadowed variables to currentLastRefresh and currentMinimumRetryInterval
- Improves code clarity and prevents potential bugs
- All tests still pass
