Elementwise inverse error function.

$$
\mathrm{erf}^{-1}(x_i)
$$

Inputs outside `(-1, 1)` produce NaN; ±1 produce ±inf. Value-domain violations follow IEEE semantics (NaN / ±inf in the result), never an error.

**Throws**

- `ClikaRT::Error`: when the input's dtype is not served for this operation (the machine-readable reason rides `code_name()`).

**Returns:** a new tensor, same shape and dtype as `input`.

```cpp
auto y = ClikaRT::ops::erfinv(x);
```
