ocaml: phase 5.1 conformance.sh + scoreboard (283 tests across 14 suites)

lib/ocaml/conformance.sh runs the full test suite, classifies each result by description prefix into one of 14 suites (tokenize, parser, eval-core, phase2-refs/loops/function/exn, phase3-adt, phase4-modules, phase5-hm, phase6-stdlib, let-and, phase1-params, misc), and emits scoreboard.json + scoreboard.md. Per the briefing: "Once the scoreboard exists (Phase 5.1), it is your north star." Real OCaml testsuite vendoring deferred — needs more stdlib + ADT decls to make .ml files runnable.
