Subject: [PATCH] Remove deprecated slot definitions and add archived versions
 for future reference

- Deleted the following slot definitions:
  - wikidata_class_slot
  - wikidata_entity_label_slot
  - wikidata_mapping_rationale_slot
  - word_count_slot

- Added archived versions of the deleted slots to preserve historical data:
  - wikidata_class_archived_20260114.yaml
  - wikidata_entity_label_archived_20260114.yaml
  - wikidata_mapping_rationale_archived_20260114.yaml
  - word_count_archived_20260114.yaml

- Introduced a new hook `usePersonSearch` for enhanced semantic search functionality in the frontend, supporting debounced queries and caching.

-          RETAINED: business_criticality is a valid domain-specific slot.
-          No standard ontology exists for business continuity criticality in GLAM context.
-          The custom hc:businessCriticality predicate is appropriate.
-          String range with enum-like values (CRITICAL, HIGH, MEDIUM, LOW) is sufficient.
-          Creating a class would over-engineer a simple operational metadata field.
-          Used by: CustodianAdministration.yaml

-          RETAINED: business_model uses schema:businessFunction - correct Schema.org predicate.
-          Schema.org businessFunction describes how a business generates revenue.
-          String range is appropriate for free-text business model descriptions.
-          Used by: CommercialOrganizationType.yaml for corporate heritage collections.
-          Creating a BusinessModel class would add complexity without semantic benefit.

-          RETAINED: cached_token is a technical API slot for LLM response tracking.
-          Integer range is appropriate for token count values.
-          Used by: LLMResponse.yaml for tracking prompt caching metrics.
-          schema:value is a reasonable generic predicate for numeric values.
-          Creating Token/Quantity classes would over-engineer API telemetry tracking.
