cacheLatestSuccess

Caches the latest Success value and keeps emitting it instead of Loading during reloads.

This is useful for scenarios where you want to show stale data while refreshing, rather than showing a loading indicator.

Behavior:

• On first Success, caches the value and emits it

• On subsequent Loading, keeps emitting the cached Success (not Loading)

• On new Success, updates the cache and emits the new Success

• Error and NotStarted are always emitted as-is

Example:

// Flow: Loading -> Success(1) -> Loading -> Success(2)
// Output: Loading -> Success(1) -> Success(1) -> Success(2)
dataFlow.cacheLatestSuccess().collect { result ->
    // Shows cached data during reloads
}
