* feat(ocsf): add JSON Schema validator for OCSF events Add openshell-ocsf-validate, which validates an OCSF event against the JSON Schema the OCSF schema server exports for the event's version, class, and declared profiles. The exports encode required attributes, at_least_one constraints, undefined attributes, types, and enum values, so the crate delegates to the jsonschema crate and only selects the schema. The exports type type_uid only as an integer, so the crate also checks that it equals class_uid * 100 + activity_id. An exported schema covers one fixed set of profiles, so the crate vendors one export per class and profile combination that OpenShell emits, under schemas/v<version>/<class>@<profiles>.json. An event whose version or combination has no vendored schema fails with the schemas/update.sh command that vendors it. Keying on the event's version lets a new OCSF version's schemas land before the emitters switch to it. The build embeds every vendored file. Top-level container is accepted unvalidated, as OCSF does not define it at the event level (#4915).

One validate_event call now covers what the per-object validate_required_fields, validate_known_fields and validate_enum_value calls checked, and adds type checks and enum checks for every attribute. Remove the validation module and the vendored OCSF object and class schemas from openshell-ocsf. The e2e suite no longer depends on openshell-ocsf directly.
