feat: add WEATHER_CHANGED event and GetWeatherInfo query

Browse source 
Fire WEATHER_CHANGED(weatherType, intensity) when the server sends
SMSG_WEATHER with a new weather state. Enables weather-aware addons
to react to rain/snow/storm transitions.

GetWeatherInfo() returns current weatherType (0=clear, 1=rain, 2=snow,
3=storm) and intensity (0.0-1.0). Weather data is already tracked by
game_handler and used by the renderer for particle effects and fog.
