⚡ Why Integer no longer stores its value as a String

Kotools Types 5.2.0 changes its experimental Integer from a string-backed model to platform-specific arbitrary-precision numeric types.

Arithmetic and comparisons now operate directly on numeric values, with parsing and formatting handled only at the boundaries.

This improves performance and scalability for large-integer work by removing repeated string conversion overhead.

The update also removes the runtime dependency on Kotlin/Native.
