Renders another `.uce` file as a component and writes the result directly to the current output buffer.

This is the direct-output counterpart to `component()`.

Component props are passed through `context.props`, and `name:COMPONENTFUNC` may be used to select a named handler exported by `COMPONENT:COMPONENTFUNC(Request& context)`.

When `name` starts with `:`, the runtime resolves that named handler against the current `.uce` file.

If the target file defines `ONCE(Request& context)`, that hook runs once per request before the file's first component or render entrypoint.

Use `component_render()` when you want to write component output directly from C++ code instead of capturing it as a `String`.

## Example

```cpp
DValue props;
props["body"] = "Hello";

component_render("components/card:BODY", props, context);
```
