commit 85bc2de6e79a0ac8366cf8f0014451a742492972

    chore(dev): bootstrap Rust and Nix environments for Darwin
    
    Configure direnv, native Darwin compiler flags, and pinned desktop dependencies. Exclude build outputs, local environments, ROMs, and saves.
    
    Start an ordered import of existing work. Feature chunks share dependencies; validate the integrated stack, not each intermediate import.
