anti dd265d7520 feat(correlation/attribution): wire bus handler, persist state (Phase 4) ...

attribution_worker.handle_observation_event now executes the full
end-to-end path:

* ensure stub identity (Phase 1)
* observations_for_identity_primitive() — new repo helper joining
  observations through attackers.identity_id, so v1's clusterer
  gets cross-attacker rollup for free
* aggregate_observations() with ValueKind dispatched off the BEHAVE
  PRIMITIVE_REGISTRY; unknown primitives default to categorical
* upsert_attribution_state() — last_change_ts locked when state is
  unchanged so the dashboard can render "stable since X"
* publish attribution.profile.state_changed only on transition;
  idempotent re-runs over the same observation set fire nothing
  (loop-prevention invariant matching ttp.tagged)

Tests:
* 5 end-to-end attribution scenarios over in-memory SQLite + FakeBus.
* test_base_repo's DummyRepo + coverage body now stub every abstract
  surface BaseRepository declares — the 6 added by this branch plus
  the 12 left un-stubbed by earlier work (BEHAVE Phase 1, TTP
  rollups, iter helpers). The coverage test could not previously
  even instantiate.
* test_aggregate_categorical's dispatcher rejection updated for the
  Phase 3 + 4 contract — ValueError on unknown kinds, not
  NotImplementedError.
