Test, Build, and Deploy / test-build-deploy (push) Failing after 52s
ocaml-eval walks the AST and yields SX values. ocaml-run / ocaml-run-program wrap parse + eval. Coverage: atoms, vars, app (curried), 22 binary ops, prefix - and not, if/seq/tuple/list, fun (auto-curried via host SX lambdas), let, let-rec (mutable-cell knot for recursive functions). Initial env: not/succ/pred/abs/max/min/fst/snd/ignore. Tests: arithmetic, comparison, string concat, closures, fact 5 / fib 10 / sum 100, top-level decls, |> pipe.
