Add a Cite Us section to the README with BibTeX citation info, and
align it with docs/citation.md (author/organization: Semantica, 2026).
Update LICENSE and docs/project-license.md copyright holder to
Semantica, and replace the stale Hawksight-AI GitHub org slug with
semantica-agi across READMEs, plugin manifests, cookbook notebooks,
and GitHub templates.
- Bug 1: replace dict .get() with dataclass attribute access on
AssociativeClass (name/connects/temporal/properties)
- Bug 2: add full URI to every ontology property and use BASE_URI-prefixed
URIs for all relationship types so TripletStore stores hr:<name>
instead of urn:property:<name>, fixing SPARQL PREFIX hr: queries
- Bug 3: filter None values from EmploymentEvent properties dict so
open-ended employment does not store the literal string "None" as endDate
