Polyfill strategy and known behavioral differences across architectures

Magetypes aims for API parity across x86-64, AArch64, and WASM. Wider types are polyfilled on narrower hardware, and the API surface is identical — but a few behavioral differences exist between architectures.

  1. Polyfills — How f32x8 works on 128-bit hardware, implementation_name()
  2. Behavioral Differences — Operators, shift semantics, blend signatures
