Announcing Rust 1.94.0

Rust 1.94.0 introduces array_windows, Cargo config inclusion, and TOML 1.1 support alongside several stabilized APIs.

• •array_windows adds a const-length slice iterator returning &[T; N] items, allowing pattern destructuring to infer window size at compile time
• •Cargo config files now support an include key to compose multiple .toml config files, with optional path support for environment-specific configs
• •Cargo now parses TOML 1.1, enabling multi-line inline tables, trailing commas, \xHH escape characters, and optional seconds in time values
• •New stabilized APIs include LazyCell/LazyLock getter and mut variants, Peekable::next_if_map, x86 AVX-512 FP16 and AArch64 NEON FP16 intrinsics
• •Math constants EULER_GAMMA and GOLDEN_RATIO added for f32/f64, and f32/f64::mul_add is now stable in const contexts
