Annotation Interface NativeStruct

@Target(TYPE)
@Retention(RUNTIME)
public @interface NativeStruct

Marks a record for compile-time metadata and struct layout generation.

The annotation processor generates a <RecordName>_NativeStruct class that registers:

• Record component metadata in RecordRegistry (replaces Class.getRecordComponents() for TeaVM compatibility)
• PACKED and STD140 struct layouts in StructLayout

This enables the full engine pipeline (StructLayout, SlangParamsBlock) to work on platforms without reflection support. Implicitly Discoverable — the generated companion class survives TeaVM DCE.
