feat(env): NWS weather alerts, NOAA space weather, tropospheric ducting

- Environmental feed system with tick-based adapters
- NWS Active Alerts: polls api.weather.gov, zone-based filtering
- NOAA SWPC: Kp, SFI, R/S/G scales, band assessment, alert detection
- Tropospheric ducting: Open-Meteo GFS refractivity profile, duct classification
- !alerts command for active weather warnings
- !solar / !hf commands for RF propagation (HF + UHF ducting)
- Alert engine integration: severe weather, R3+ blackout, ducting events
- LLM context injection for weather/propagation queries
- Dashboard RF Propagation card with HF + UHF ducting display
- EnvironmentalConfig with per-feed toggles in config.yaml
