Assigns a new value, forwarding through references when possible. String, pointer, and f64 overloads set scalar nodes. `set(DValue)` copies the source's current type and payload. `set(StringMap)` creates a map-shaped value with each string entry as a child.

```cpp
DValue user; user["name"].set("Ada"); user["score"].set(9.5);
```
