MNALIB::MnaOpRegistry is the lookup table that the rest of the library hits whenever an opType string needs to be resolved into something runnable. It stores two parallel maps: one from op type to MNALIB::MnaOpSchema (used by MnaGraph::validate and by GUI editors to render attribute forms), and one from op type to an OpFunc lambda (used by MNALIB::MnaGraphExecutor to run the node). External / CLI / Script ops typically only register a schema; in-process ops register both.

loadRegistryFiles searches upward from the application directory for resources/mna/ and asks MNALIB::MnaRegistryLoader to ingest mna-registry.json plus every drop-in under mna-registry.d/, so new operations can be added without rebuilding the library. missingOps reports the op types referenced by a loaded project that the current process cannot resolve — the simplest way to detect a stale or partial install.
