Module builtins 

Built-in ALTREP data implementations for standard Rust types.

Provides AltIntegerData, AltRealData, AltLogicalData, AltRawData, AltStringData, and AltComplexData implementations for:

• Vec<T> — owned vector (most common)
• Box<[T]> — boxed slice
• Range<T> — lazy arithmetic sequences (integer, real)
• &'static [T] — borrowed slices (zero-copy from static data)
• [T; N] — fixed-size arrays
