Registry: submit UOGTO to BARTOC

[edithatogo]

Parent roadmap: #65

Conductor track: portfolio_registry_submission_roadmap_20260721 (conductor/tracks/portfolio_registry_submission_roadmap_20260721/).

Complete the named registry deliverable with authoritative evidence. Keep the issue open while eligibility, submission, acceptance, publication, or identifier resolution depends on an external party.

Repository implementation is complete in PR #101: BARTOC handoff metadata, stable namespace/release/DOI/RDF/license/ORCID evidence, and generated registry packet coverage. Remaining work is external submission and curator disposition.

Hosted reconciliation: registry implementation PR #101 (#101) is merged. Repository-side work and validation are recorded; external publication, provider response, DOI resolution, and acceptance remain open gates.
