  [LifetimeSafety] 'erase' does not invaldiate node-based containers (#181216)

```cpp
// This pattern was previously flagged as a lifetime violation
for (auto it = my_map.begin(); it != my_map.end(); ) {
    if (should_delete(*it)) {
        my_map.erase(it++); // Safe in map, but flagged as invalidating 'it'
    } else {
        ++it;
    }
}
```
