⚠️ Deprecation Notice

Inline script metadata parsing is deprecated (#3397 @romangolev).

It is now opt-in only due to performance impact in the new C# loader. Extension authors should migrate metadata to bundle configuration files as future versions will progressively remove inline parsing support.
