DomainDig v3.5.0: Expand the Pro+ Data+ intelligence layer with deeper local historical context

and inferred enrichment.

- add derived intelligence fields for provider fingerprinting, classification,
  ownership transitions, hosting transitions, subdomain history, risk signals,
  and inferred timeline events
- expand DNS history beyond A/NS snapshots to retain A, AAAA, MX, NS, TXT, and
  CNAME change state
- persist enriched intelligence in snapshots and history entries so analysis is
  local-first and incremental
- add a dedicated Data+ Intelligence panel to current and historical domain
  detail views
- surface intelligence events in timeline rows and include Data+ changes in diff
  output
- preserve non-blocking inspection behavior by keeping enrichment additive to
  the main lookup path

This makes Pro+ materially deeper for investigative workflows by improving
historical ownership visibility, infrastructure context, hosting change
detection, subdomain intelligence, and explainable risk signals.
