Spinel brings Ruby AOT native binaries

This is a legitimately ambitious Ruby systems project, not just another syntax-layer experiment. If it matures, it could make Ruby startup and throughput far more competitive for compute-heavy workloads, but the current value is still mostly for enthusiasts and compiler hackers.

• –The big hook is whole-program type inference plus native code generation, which is a much stronger bet than incremental JIT tuning.
• –Self-hosting matters: it suggests the compiler stack is already coherent enough to compile itself into a native binary.
• –The benchmark claims are promising, but they’re measured against miniruby, so the real-world gap versus standard Ruby deployments will be smaller in many apps.
• –Feature support is still selective, which means this is more “early compiler prototype” than drop-in replacement.
• –For Ruby’s ecosystem, this is notable because it pushes AOT-native execution further into a language long dominated by interpreted and JIT approaches.
