Mojo vs Rust for recursive heap allocation performance

Claim: Mojo outperforms Rust in recursive heap-allocated vector ops — 1.2s/1.5MB vs 9.1s/10GB (7.6x speed, 6800x memory). Opposing view: may reflect Mojo's specialized memory model, not general-purpose perf. Recipe: Full source code + hyperfine/valgrind profiling commands. Source: https://modular.com/blog/mojo-vs-rust
