jlview: Zero-Copy Julia to R Array Bridge via ALTREP
Provides zero-copy R views of Julia-owned arrays by implementing ALTREP (Alternative Representations) classes that return pointers directly into Julia's memory. The package integrates with 'JuliaCall' and uses C-level finalizers for safe cross-runtime garbage collection.
