Rust 1.96.0 released with new Range types and WebAssembly improvements

The Rust team has released version 1.96.0 of the programming language, introducing several key improvements. The update stabilizes new Copy-compatible Range types (core::range::Range, RangeFrom, and RangeInclusive) that implement IntoIterator instead of Iterator, enabling safer storage of slice accessors in Copy types. Developers gain new assert_matches! and debug_assert_matches! macros for pattern validation with better error reporting. WebAssembly targets now treat undefined symbols as linker errors by default rather than converting them to imports, helping catch build issues earlier. These changes follow RFC implementation and community testing through Rust's beta channel.
