normalizers/nws: add NWS alerts normalizer and canonical alert mapping
- Introduce AlertsNormalizer to convert Raw NWS Alerts (SchemaRawNWSAlertsV1)
into canonical WeatherAlert runs (SchemaWeatherAlertV1)
- Add minimal NWS alerts response/types to support GeoJSON FeatureCollection parsing
- Map NWS alert properties (event, headline, severity, timing, area, references)
into model.WeatherAlert with best-effort timestamp handling
- Establish clear AsOf / EffectiveAt policy for alert runs to support stable
deduplication and snapshot semantics
- Register the new alerts normalizer alongside existing NWS observation and
forecast normalizers

feat(nws, normalizers): add NWS hourly forecast normalization and enforce canonical float rounding
- Implement full NWS hourly forecast normalizer (raw.nws.hourly.forecast.v1 → weather.forecast.v1)
- Add GeoJSON forecast types and helpers for NWS gridpoint hourly payloads
- Normalize temperatures, winds, humidity, PoP, and infer WMO condition codes from forecast text/icons
- Treat forecast IssuedAt as EffectiveAt for stable, dedupe-friendly event IDs
- Introduce project-wide float rounding at normalization finalization
- Round all float values in canonical payloads to 2 decimal places
- Apply consistently across pointers, slices, maps, and nested structs
- Preserve opaque structs (e.g., time.Time) unchanged
- Add SchemaRawNWSHourlyForecastV1 and align schema matching/comments
- Clean up NWS helper organization and comments
- Update documentation to reflect numeric wire-format and normalization policies
This establishes a complete, deterministic hourly forecast pipeline for NWS
and improves JSON output stability across all canonical weather schemas.
