feat(wzdx): WZDx adapter + CENTRAL_TRAFFIC family bootstrap (v0.9.0)

Browse source 
Opens Phase 4 transportation aggregation (Design B, Central-direct). New
registry-driven wzdx adapter polls the FHWA WZDx Feed Registry, fetches each
eligible v4.x GeoJSON feed concurrently, and emits work_zone events into the new
CENTRAL_TRAFFIC stream. Production code; central-supervisor AND central-gui
restart (new adapter class + stream + ADAPTER_GROUPS). Ships disabled.

First adapter to use the category/subject split: category="work_zone.wzdx" (GUI
event_type "work_zone" via split_part) while the NATS subject is
central.traffic.work_zone.{state}. Subject state from the registry row, geocoder
state as fallback. Severity from vehicle_impact (all-lanes-closed=3,
some-lanes-closed=2, all-lanes-open=1, unknown/missing=1). Feed filter
geojson + active + needapikey=false + version 4.x (21 of 39 feeds). 600s cadence.
Dedup composite <data_source_id>:<feature_id> in the shared cursors.db; stateless
discovery (no conftest isolation entry). enrichment_locations uses the canonical
("latitude","longitude") paths.

Full suite: 739 passed, 1 skipped (central and unprivileged zvx, 3x each).
