🤖 Augment PR Summary

Summary: This PR expands JSON-LD annotations across the schema library to standardize how numeric “quantity” schemas can be expressed in RDF.

Changes:

• Adds x-jsonld-constants with a fixed QUDT hasUnit IRI for many SI (base/prefixed/derived), non‑SI, and ISO unit schemas
• Adds x-jsonld-type set to http://qudt.org/schema/qudt/Quantity on those quantity-like schemas
• Adds x-jsonld-value set to http://qudt.org/schema/qudt/value to indicate where the numeric literal should be emitted
• Adjusts ISO 6709 latitude/longitude schemas to be plain number types (no longer $ref the degree unit schema) to avoid JSON-LD degree-quantity annotation
• Documents the latitude/longitude JSON-LD rationale via $comment

Technical Notes: The new annotations consistently bind schema instances to QUDT unit IRIs, enabling downstream JSON-LD tooling to emit typed quantity nodes with fixed units while keeping validation constraints intact.
