New graphify/extractors/ocaml.py handles both the implementation grammar
(language_ocaml, .ml) and the interface grammar (language_ocaml_interface,
.mli). Emits nodes for modules, top-level/module-level values and functions,
types and their variant constructors; edges for defines/contains, open ->
imports_from, and application -> calls. Qualified paths (Geo.area) resolve to
the final value name, not the module qualifier; local let ... in bindings do
not mint nodes or steal call attribution. Cross-file open/call targets are
sourceless stubs so the corpus rewire collapses them onto the unique real
definition (no #1402 sourced-stub leak).
Wired into detect.py (CODE_EXTENSIONS), extract.py (dispatch +
_EXTRA_FOR_EXTENSION), pyproject.toml ([ocaml] extra + all + dev dep), and
README. Adds tests/test_ocaml.py (behind importorskip).
