* feat: support static buffer constructors and prototype methods - Preserve typed-array constructor identity and shared storage across JavaScript class APIs. - Support chained indexed assignments and mutable prototype methods with native receiver dispatch. - Compile Three.js geometry merging, instancing, and keyframe interpolation without a JavaScript engine. * fix: preserve native collection and dispatch semantics - Preserve typed-array identity in collections and JavaScript argument evaluation. - Keep symbol-backed fields and unreachable methods on their existing static paths. - Restore compiler bootstrapping and deferred class diagnostics. * fix: preserve inferred returns in native compilation - Update recorded return statements in place so native compilation preserves mixed JavaScript return values. * test: update inferred array coverage expectations - Recognize heterogeneous writes supported by shared JavaScript array storage.
