8 design decisions: PrometheusConfig (grafana_url/datasource_uid + grafana_api_key
secret), /api/ds/query body per widget kind (window presets -> intervalMs/
maxDataPoints), normalize_grafana_frames refactored from 65bae95 into
prometheus_range.py (shares label-dedup with matrix normalizer), MetricSource
adapter, gateway-path status check, git mv widget renames, startup old-config
validation. 2-slice plan. 3 source findings flagged.
