Add a JIT compiler using Cranelift that compiles Lux functions to native machine code. Achieves ~160x speedup over the tree-walking interpreter (fib(30): 11.59ms JIT vs 1.87s interpreter). Supports: arithmetic, comparisons, conditionals, let bindings, function calls, and recursion. Compile time overhead is minimal (~500µs). Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
