Parser: module F (M) (N) ... = struct DECLS end -> (:functor-def NAME
PARAMS DECLS). module N = expr (non-struct) -> (:module-alias NAME
BODY-SRC). Functor params accept (P) or (P : Sig) — signatures
parsed-and-skipped via skip-optional-sig.
Eval: ocaml-make-functor builds curried host-SX closures from module
dicts to a module dict. ocaml-resolve-module-path extended for :app so
F(A), F(A)(B), and Outer.Inner all resolve to dicts.
Phase 4 LOC ~290 cumulative (still well under 2000).
