Add a marketplace integration for the OpenCTI platform (GraphQL API, compatible with OpenCTI 5.x/6.x), built on the Python pycti client and run from a remote engine. 26 commands: observables (list/create/delete/field update/add/remove), indicators (list/create/update/field add/remove, types), incidents (list/create/delete, types) with an OCSF ingestion mapper, relationships (list/create/delete), and reference data (organizations, labels, marking definitions, external references). - Ingestion: get_incidents to an OCSF finding mapper + an OpenCTI Incident type. - Auth: user API key (Bearer) via pycti; requires pip install pycti on the engine host. - Scripts are self-contained (INTEGRATION_SECRETS/INTEGRATION_INPUTS in, JSON out) following the established marketplace pattern.
