Standards: Decide and document OGC certification path

[mikemcdougall]

Problem

We run OGC CITE conformance tests locally/in CI, but there is no documented path for official OGC certification or published baseline results.

Evidence

• OGC Features conformance guide: docs/cite-conformance-testing.md:1.
• OGC API Tiles conformance guide: docs/cite-tiles-conformance-testing.md:1.

Goal

Decide whether to pursue formal OGC certification and document the process/baseline results if so.

Tasks

• Decide scope: OGC API Features (Core/Transactions), Tiles, etc.
• Document submission steps and required artifacts.
• Publish baseline conformance results (versions + pass/fail summary).

Acceptance criteria

• Clear go/no‑go decision on certification.
• Documentation updated with submission steps or rationale for deferring.
• Baseline results published if proceeding.
