Graham McIntire 3ea2548114 Phase 8: 5-minute METAR ingestion pipeline
NCEI ASOS 5-minute data client (Weather.NceiMetarClient):
- fetch/3 pulls per-station monthly .dat files from NCEI C00418
- parse/1 decodes the fixed-width METAR format including precise
  T-group temperatures (T02110094 → 21.1/9.4°C)
- metar_5min_observations table: schema-identical to
  surface_observations, separate table to avoid mixing cadences

Weather.recent_surface_obs/3 prefers 5-min data when available,
falls back to the hourly surface_observations table.
