Summary

• parse board attributes and component custom IDs from the new Arcweave JSON export
• expose eligible boolean, integer, float, and plain-string attributes as board- or component-scoped Arcscript variables while retaining stable attribute IDs
• keep mutable current values separate from authored defaults so reset and resetAll work across interpreter invocations
• update the C++ interpreter ABI integration and vendor tested Release libraries for Windows x64 and macOS arm64
• add an import/interpreter automation test, fixture, and scoped-variable documentation
